Unable to use after updating the latest version 2.0.81

After the updated version, I opened the deck to study, but no content appeared. I can only view the content of the card in “Browse”. Please help me find out what might be the reason. @dae

Everything is normal after the Web update.

Thanks for the report - this was another iOS12-specific issue. I sent an update to Apple this morning, and it will hopefully become available in 24-48 hours.
