Hey @zeitmeister @fpuser2, thanks both for your feedback and @zeitmeister I will try the workaround suggestion!
Anyway, now that the issue is confirmed I have added this thread to https://forum.fairphone.com/t/known-reproducible-and-reported-issues-of-the-fairphone-5/ for additional visibility.
In addition today I got and installed a security update, looking forward to checking if it had any beneficial effect on behavior.
