Google sheets not working

hello i started using brave about a week ago , at first it seemed really good but there 2 major problems ive found so far one is online games just will not open , ive tried adjusting flash and other browser settings but nothing works , and another prob is it corrupted all my google sheets and that really needs to stop happening before i come anywhere near again , why have a browser ext that clearly isnt compatible all the text data on all my sheets moved and in some cases merged with one another i had to spend quite a lot of time fixing them in the last 2 days , only today realising that restoring from very recent history on brave is no good but do the same thing on chrome browser fixes the problem to a large degree

@gergynamfauk have you tried out sheets behavior with disabled shields? I was facing the same issue and with disabled shields, sheets are working as expected.
