Hi Gazumped, thanks a lot for your reply, sorry for the red flags, definitely due to my unfamiliarity with right terminology, and trying to explain my problem as succintly as I could. (Not to mention the disappointment and irritation for the problem. I am just an average person that used this app to save same data I wanted to keep.)
1) It's the same thing Boot 17 said, I agree, it seems like that's what happened, but I cannot figure out how, I use Evernote on this device only, and basically until yesterday never logged out but used it very regularly.
2) "Forced" as in I was in the middle of writing a note when it popped "there is an update, install. And it was ok to me, since there had been no update prompts in a while. From legacy to 10? Maybe, I have no idea sorry.
3) Apparently it wanted me to drop a sync device (that I never used I never even remembered I had it, I even thought I had only the one - nevermind the web version) After, it dropped the credit card thing, now I see the homepage, but still stuck at five years ago.
4) Yes, that's the point, they must be out there somewhere, (I do hope!). If I could only access them.. That's all I want.
5) How long would it last, a "suspension"? I will wait a few days then and try again... Then writing to Support...
