It is still early beta, but running without any problems whatsoever. Even with Evernote, until this last update. And I haven't changed anything. Installing a beta means that you might run into problems, I realise - and accept - that. What I found strange here though is that it ran perfectly fine on 13 with the previous version. And it doesn't sound like a iOS 13 issue to me, as there are many more freezing problems mentioned in this forum, with various versions - both from iOS and Evernote.
