To be honest, I don't really like rolling back iOS releases. Although I recognise that I dive in head first off a bridge into cold water every time I go with (any) OS beta, I kind of expect apps to sort of follow within some time - but we're about to hit beta 4 of iOS 13, and it's been out for over a month, but Evernote has not kept up. I know they often don't work, have bugs, etc - I've been using OS betas since Windows 'Chicago' and Win'97 Nashville (and I use final versions of MS OSs, which aren't necessarily always better :D ), so I know a bit about bugs; but it should really not make basic use apps like EN stop working completely.
I don't like many things about OneNote (lack of geotagging, others) but it works, which is really frustrating to not be the state of things for Evernote. I really don't want to switch, but I am hopeful that the EN team has access to the same iOS beta I do, and has at least a version that can pull up a note and not lock up - I don't think I'm asking for the world here, to be fair.
