Thanks PinkElephant, I probably will if this keeps up. I get these error messages every now and then and they typically resolve themselves, it's just today they're really persistent.
And re: the App Store, I'd been having an odd issue where the App Store thought I was on one plan and Evernote thought I was on another, so I was getting charged for the features I wasn't getting for a time. Talking with EN support made it seem like it was some kind of miscommunication between Apple and Evernote, which by all accounts seemed like a bit of a freak occurrence. Eventually, and weirdly, I found that Apple and Evernote both showed me as being on the base plan again, so I went to upgrade and the App Store kept saying I couldn't, because I was already using Professional, despite the previous screen showing my subscription at the Personal level.
Idk, I got tired of it so I just cancelled and re-subbed, which fixed the discrepancy, but now I'm getting these error messages 😂🙃
In the end it'll all get figured out, but I've had the strangest luck with this stuff on Evernote.
