@kayeelbie,
Can you check and see if Brave appears in the list of apps allowed to send you notifications? In Windows Settings --> Notifications and Actions,
The browser showed ads yesterday but it doesn’t show any ads today. Windows focus assist setting is off, notifications setting is on and brave is listed.
I have version 1.10.97 Chromium: 83.0.4103.116 (Official Build) (64-bit)
Other than OP – If you’re chiming in on this thread because you also have issues viewing ads (or ads not displaying), please open your own thread on Community with all the necessary information so that we can properly address it.
