Failed to register your phone number. Update pushed, still no fix to "Failed to register your phone number. Please check your network connection and try again." On Samsung 22 ultra running One UI 5.1. Tried uninstalling, reinstalling, resetting network, using mobile network, restarting phone, using desktop to add phone number, etc. No use. Recaptcha fails on my OS and won't allow phone to be registered. I'm trying to start a family update chat for my mother who has terminal cancer. This is her preferred platform despite all the issues. Please help.
