Matomo version: 3.13.3
After the login from IE11 the page shows the top menu and the sidebar but instead of a report there is an error message saying that the session has expired.
Could this be because of the use of
SameSite: Lax for the cookie?
might be possible. IE 11 only has partial support in later releases 🤔
Whatever that means exactly. Unfortunately we have customers still using it...
The problem seems to the ajax call(s) that get the reports.
Nevermind. Are you using Windows 10 with latest IE 11 or an older Windows?
Did some more testing on that. Seems not to be caused by the samesite option. Seems to be caused by the invalid session expire as well. And should already be fixed with #15633
Thanks. I'll test this with 3.x-dev branch tomorrow.
