Bug description

On iOS and after the upgrade to the latest version (5.19.0), the app was disconnect from the server i.e. unable to send or receive messages. Yet I'm still able to send and receive messages on desktop (a linked device to the same account).

And now when I try to register once again using the same number, I'm getting this error message "Invalid response from service."

Thanks for reporting this! This issue should be fixed in 5.19.1. It's currently waiting on app store review but it should be available sometime soon. Hopefully in the next few hours. Please let us know if you're still hitting this issue after updating.
