Evernote web problem only, it's been happening for the past month or so but I haven't gotten it before. There are two issues and I think they're related. I've only been doing text notes recently, so that's when it's been happening. I'm on Windows 10 using Firefox, if that's relevant info. No noticeable internet problems while this is happening, I can browse just fine on other sites, so it's not a connectivity issue.
Issue 1: I'll type in a note, think it's synced, but then it doesn't. I lose most of what I was typing, but not all of it (sometimes it'll just stop mid-sentence or mid-paragraph). Usually only happens if I'm typing a lot and making a large number of changes, upwards of 5 minutes on the same note. If I'm only one for 30 seconds, it seems like it's fine
Issue 2: usually also while typing a lot on the same note and not all of it saves (i.e. the above issue), then I'll have duplicates of the bad version of the note, anywhere between 5 or 50. For example, I'll finish typing and close out of Evernote. If I re-open Evernote, I now have 10 version of the note I was just typing, at "5 minutes old, 5 minutes old, 6 minutes old," etc.
If I just quit typing and allowed it to sync, the most recent version should be under a minute old. Further, all the duplicate notes appear to be at the same level of incompleteness (usually), so if it stops saving it midsentence, the duplicates are also at the same spot midsentence. (not always the case though, sometimes each version will have slightly more information than the previous; but even in such cases, none of them have all of it)
What it's meant for me is I've stopped using Evernote as much, I don't want to put in a ton of time taking good notes only to have half of them vanish. Sometimes before exiting, I'll copy the text of the note, re-open Evernote, and if it didn't sync then I'll paste over the note. Not a good workaround, especially long-term.
