An app does not work?

iodé integrates an android operating system freed from major snitches. Therefore, few apps might dysfunction, though they might only do so temporarily. Also, you can try the web version instead of the native version of the dysfunctional app.
If you encounter issues with a given app, thanks for letting the iodé support know at this address: support@iode.tech.
You will find a non-exhaustive list of the concerned apps here.
