Pending BAT decreased

Recently started using Brave app on Android phone.
Kept an eye on the pending rewards, due to payout on Apr 5. Looked like it was .01 to .02 per ad, seen 78, was around 0.9BAT. Then after viewing another one, pending BAT went down to .10 when I was expecting to finally reach a full token. Is this a known issue? Will the pending BAT be restored?

Screenshot after the pending rewards decreased, but the ads counter remained correct.

Same thing happening to me on mobile

they are mining with our hardware, they are not paying to anybody, all the bats decrease or just simply disapear.

Same issue with pending rewards. It drastically decreased to half?
