Try the following to fix this:
- Completely delete the app data (in Android this is usually under app info > Storage > Clear data). Not just the cache option, ensure you clear "data", which is more comprehensive. You will be logged out but can login again and download clean assets.
- If the above fails: Uninstall then install the application again. This is a more aggressive way to clear the corrupt data, but only use it as a last resort if other options don't work.
Let us know if this helps, because the alternative is waiting for a patch, which could take up to a week in Google Play, for example.
