Solved! I went to my profile and under Security I saw the Backup Phrase wasn’t confirmed (even though I had made a note of the phrase when I first opened an account). I clicked on Backup Phrase, took a note of the words (same as I had written down) and then answered the question – what is your 2nd, 3rd and 11th word. After that is put “confirmed” by Backup Phrase. I was then able to send btc.
I’d suggest to the developers that they put a more meaningful message than “over your limit” if this is in fact the issue. And why would it let me send $5 but not $50?! Some rule written somewhere in the software that isn’t brought to the user’s attention.
