- The link from the ad points to a page that does not have the code snippet installed on it. As a result, Yandex.Metrica cannot correctly register the referral source. When a user goes to the next page (where the code snippet is installed), your site is recorded as the session source in reports. To avoid these types of errors, make sure that the code snippet is installed correctly on every page on the site.

This message may appear for several reasons:
Session Replay is not enabled automatically when creating a tag. To learn how to enable it, see the section Enabling and configuring Session Replay 1.0.
When enabling Session Replay, don't forget to click the Save button. Otherwise, report data will not be displayed.
Yandex.Metrica protects users' privacy and ensures that all collected information is depersonalized. This is why some data is not fully disclosed. This includes data that is calculated by Yandex algorithms, for example, socio-demographic data (gender, age), login page addresses, search phrases, and information about robots. Such information is provided only if there are more than 10 users in the sample.
This information can't be shown in the report, since Session Replay records the actions of each user individually.
This may be caused by the following reasons:
A certain percentage of visits to any site may not display any activity. This happens either because nothing actually happened on the page during the session, or because the actions could not be recorded.
Reasons for nothing happening on the page:
Reasons for actions not being recorded:
No, the load on your site will not increase, because all the user actions are recorded in users' browsers after your webpage has loaded.
Depending on the page size and viewing time, the data transferred per session ranges from 200 bytes to 4 kilobytes (this is less than 5% of the average page size in the internet). Such an increase in traffic will be negligible compared to the amount of data used when visiting your site.
If there are a large number of HTML markup errors (such as unclosed tags or incorrect nestings), this may lead to inaccuracies in session replays. Session Replay usually adapts to such errors, but having correct HTML structure on site pages is preferable.
Session Replay supports most modern computer browsers. There is limited support for recording sessions in beta versions and in certain mobile browsers.
We recommend keeping your browser updated to the latest version available. Session playback is supported in these browsers: Yandex Browser, Google Chrome, Firefox, Safari, Opera, and Internet Explorer.
In Safari 12, the click map, link map or scroll map page may load endlessly due to an option in the browser settings.
Yes. Sessions on pages with flexible layouts will be replayed correctly, even if the resolution of the user’s screen is not the same as the replay screen. During playback, you might see small cursor jumps due to a different relative positioning of elements on the recorded and replayed pages.
Session Replay does not record passwords and makes no attempt to log in to a site on behalf of a user. Therefore, the player loads the login page, just like any other user who has not logged in.
Most likely, the form sends data using the POST method.
When loading data to the player, Session Replay only uses the
GET method. This is because POST requests usually lead to actions such as submitting a form, making an order, and so on. Session Replay would be simulating an actual user if it used the POST method, so every time you viewed such a page using the player, you would get a duplicate request or repeat order.
Session Replay only records user actions performed in the HTML sections of a site. In addition, user interactions with Flash elements are not recorded. Only mouse movements over these elements are recorded. The cursor may disappear when playing these movements. This is due to the fact that Flash elements are by default displayed above the page's content in the browser, including the cursor displayed by the player.

You probably have some sort of protection from rendering pages within a frame. It may look something like this:
In order for sessions to replay correctly, you’ll need to delete this code.
No. Session Replay does not record what is entered in a
password type field.
To prevent information from specified fields from being recorded, set the CSS class -ym-disable-keys for them. This class can be used for marking fields with private information.
When replaying sessions, sometimes a duplicate form may be submitted in the name of the user on the site (for example, another product is added to the shopping basket).
To prevent this, set the CSS
-visor-no-click class for form elements:
<form action="/login" method="post" class="-visor-no-click"></form>
Yandex.Metrica stores session recordings for the previous two weeks.
