Hello,
I should have 296.196 BAT but only showing 264.19553 BAT in my wallet. I also have 10.750BAT from January 2021 just sitting there and I never got credit for it either after January 5.
Update 01/24/2021
I think I know what the problem is now. I have two laptops. One windows and one Linux. The Linux one shows 264.19553 BAT and the windows one shows 296.196 BAT. I am getting bat from the Linux laptop but not from the Windows laptop. It looks like this has confused Brave software. Seems to be a syncing issue to me.
