I uploaded this deck of Japanese sentences yesterday:
Today I tried to updated the deck, but when trying to update, I am permanently stuck on this “Processing screen”:
Just before I tried to update the deck that I shared on ankiweb, I changed the card template a bit then did a sync.
I’m using Anki 2.1.49 o Windows 7.
It only took, like, 20x longer than the usual to upload the deck, but eventually it worked.
I will not delete this thread, in case someone searches for this same issue on Google.
