To me this looks like an issue retrieving information from the server. It would explain why he cannot see his Pokemon, the Poke-time, his money, etc.. Alongside that, the map isn't loading.
What you could try is a solution for a issue that was similar to this. When you log in just afk on PRO until the server kicks you for being afk. This could take up to 30 minutes, based on reports from previous issues, however it could fix the problem entirely. Let me know if it works.
Thnx man i let it afk and it fixed after some hours thnx a buch
