The Core Team is aware of the phone verification issues, but there is no timeline for a fix. Currently, the official stance is that Pioneers don’t need to do verification with Facebook or phone. They can mine and maintain the Pi mined even if they’re unverified, but members verified through either Facebook or Phone number will have more credibility in the network, e.g. eligible to certain chats and giving more confidence to people when others add members to their security circles. The warning messages in the app are not consistent with the official stance and need to be changed. I hope this helps you, additional reading below.
