Brave Wallet Emptied & No option to convert Rewards to wallet for a long time

I had almost 700 BAT in my wallet and now all gone! 0 BAT! I deinstalled and reinstalled Brave browser because every month for the past multiple months I haven’t got a reward button… used my phrase sensitive password afterwards and all I see is 0 BAT.

2 issues - No reward prompt every month and no BAT in my browser wallet

Please help because I’ve been loyal to brave for a heckin long time…and now I’m just pissed off
