if i try to connect button is completely inactive, does absolutely nothing, while the rest of them working fine, i dont know, something happened to my account without even actualy touching it for month, brave rewads absolutely not working for a very long time now, it was years ago, received reward once and after it completely gone, i had a balance left on my account and now nothing in there.
what can i say waste of time probably, only good thing that is still working is add block, even that one sometime fails.
Could you restart Brave and restart your device once?
