Clozemaster not loading lessons

AlexJD

For some reason when I try load a lesson in the language learning app Clozemaster it just gets stuck at "Loading". I know it use to freak out if Google Speech Reconition and Sythesis wasn't installed but it is on my device. I've enabled compatibility mode the Clozemaster too. It's a ReactNativeJS app. Does anyone else have this app working on GrapheneOS or are there any known issues before I start diggging the logs? Everything is up to date, done all the obvious clearing storage/reinstalling/permissions/enabling compatibility mode.

It looks like it's breaking around here (MP3 decoder init then failure) when you press play to start a lesson. Clozemaster works okay on my old stock OS Pixel 4a (5G). I do have the full logs if needed but the things that seem to stand out are below:

If there aren't having any issues with the app on stock OS but are on GrapheneOS, then there's your answer.

AlexJD

Yup. With compatibility mode on, Clozemaster still hangs. Tried to replicate that ExoPlayer/codec error with a test app but it worked fine so it's something specific to the app probably.

Clozemaster did use to work so not sure what changed or when. Given it historically use to prompt installing Google Speech Recognition/Synthesis, my uneducated guess is that something is going wrong there. I’ve installed Speech Services by Google + the Google app. Shame as it's really good.

No problem. Delete the app, login via web, then after you login Add to Home Screen from vanadium settings. Has all the same functionality as the app as far as I can tell.
