Any ideas why I have 155 BAT rewards but only 35 BAT have transferred to Uphold?

@Blue2,
This is actually a known issue right now – many other users are reporting the same thing:

Brave Ads not properly counted

Same here on Android Version, recieved round about 5-7 Ads but my estimated BAT didn’t grew up.

The team is already aware of the issue and working on a solution presently.
