Okay, so I went to boxcryptor, and in the "uploads" section it had a least 100 pictures in there waiting to be uploaded. I pressed the "X" at the top of the screen to cancel them all (nice that it is that easy), then pressed the "trash can icon" to clear everything out of "uploads."
Then I turned off file name encryption. Closed boxcryptor (all the way).
Then opened boxcryptor again.
switched over to Gallery, looked at one picture (did not rotate or modify it in any way), and boxcryptor uploaded that picture.
Now, boxcryptor has at least 100 pictures set to upload (probably more), and it's uploading pictures in random order from my gallery (I've not taken any recent pictures), and boxcryptor has previously uploaded every picture (at least once) that it is uploading again. So who knows.
Nope, I'm not clever enough to troubleshoot this, so I will end with this post. Thanks for reading my babbling... Hope it helps someone else or boxcryptor team in some way.
