Thank you for contacting Tapatalk! The photo upload issue you experience today is due to an unscheduled maintenance to fix the intermittent photo upload problems we have been seeing. The maintenance is expected to last a few more hours during which you might encounter a few hiccups still.
Sincere apologies for any inconvenience and run-about this causes.
I ended up re-installing. However, I had forgotten my Tapatalk and WS password and it was quite a process to get back up and running. I now find that I get a lot of Tapatalk notifications - new thread etc. Far more than I had before, and more than I would like. I'm not sure how to modify the notifications though.
