I'm glad I came here to check to see if anyone else had the same issue as I've had!
As soon as I realised that both my webmail and my phone app were buggered, it was probably not just a Me Problem.

It started out as not being able to search, but the situation is quickly deteriorating and now I'm unable to open pretty much any email message.
Some content seems to briefly show up and then it quickly disappears and after that, it's as if cache has been invalidated and you can't get back into it.
Edit: apparently "hybrid apps" using webviews are allowed as long as they're not "thin wrappers" for websites and provide meaningful functionality. See also: the capacitor framework.
