Message:Edge is notoriously bad and I'd been having a lot of general system-wide issues which I resolved by moving from Firefox to Opera.
Firefox used to be great, but, over the last couple of years it's become terrible.
Side note - I've talked to the Epic Table guy who says there should be no issues with that in Win 11. He tells me his personal machines - i.e. what he built and tested on - were Win 8 and Win 11 and that he's never actually used Win 10. Yes there were issues at one point, but the timing of that lines up with when Epic Table moved it's hosting to a new server company, so we may have just overlapped a back end problem with your Win 11 update.
Yeah, yeah, "step back," but you've already paid for Epic Table and I, personally, always liked it better than Roll 20. Multiple tabs, not having to key in stupid macros for dice, blah blah.
Also the Epic Table site does have articles about migrating all Ref data between computers.
