Not sure since when, but the page overlay doesn't really seem to work anymore.
It only shows the loading screen but doesn't actually do anything:
There are no errors in the console, no failed HTTP requests and not even any HTTP requests apart from the assets of the page (so no calls to the API)
This can also be reproduced on demo.matomo.org
and has been reported on the forum:
Same here, tested on 3 different instances (MTM 3.11)
This should have been fixed in https://github.com/matomo-org/matomo/pull/14766
Fix works, thanks, Thomas!
