Hmmm... Maybe this is an unrelated problem. Or it's the same problem that I've incorrectly attributed to my mint consolidation, although my problem pretty much disappeared as soon as I went to a single mint.
A corresponding problem I was having was that about half the time, my transactions weren't showing up in my transaction log even though they were successful. I think Minibits has flagged that as a bug that will be resolved in a future release.
Is it only Alby zap sends you're having trouble with, or is it every provider?
