Issue with Rewards

All day yesterday (5th Nov) I was waiting for the claim button to appear but nothing happened. Now( 04:35 6th Nov) I go to check and I still don’t have the claim button but the pay day has changed to 5th Jan and the amount of Pending BAT has changed to a smaller amount an amount that also doesn’t make sense as it contradicts the viewed ads counter. It says 2.1 BAT pending and notifications received 34 ( so 34x0.05=1.7).
Can anyone help?
Also can someone clarify how the BAT pending is calculated? is it for example calculate based on the 1st of the month until the end of the month or is it from claim day to claim day? And also is it a time on the pay day preset that the claim button should appear (e.g. 00:00 GMT)?

Thank you
Gabriel

I received my rewards on the 6th of the month. I get an email saying the rewards are in my uphold account.
