[CLIENT] Unable to sub for any team of the same tier or any tier. Not team captain. Played yesterday

I'm verified, honor level 3 and fully ranked. I played yesterday. Not team captain. I was at first and it was saying i was ineligible. I have tried several teams since then and it either says ineligible or it says unknown error. I'm completely screwed out of clash rewards today... I just wanted that sweet sweet banner...

No idea how to reproduce or why it happened or I would detail how to reproduce.
