All my BATs have gone

Hello community, I’ve been using Brave for some years and could acumulate around 23 BATs on my phone just from rewards, today they were gone. I tried to log in with Uphold, but it just showed my pc BATs, so dissconected that, momentarily I could see my 23.some BATs and claim decembers reward, but they dissapeared again, now I have nothing.
I haven’t used the Brave Wallet yet btw.
Hope it is just a visual bug T_T
Any help/guide?
Thanks!
