The new version of Tuya in 2024.2.0, which forces you to re-configure with a new method, is broken.

Has anyone managed to get it working?
I found a workaround in the github issue thread - you need to change to the default theme. BUT I also had to restart Home Assistant as the app then said the generated QR code had expired.
