continue to have youtube quota exceeded problem

hi, after updating to the latest version of kodi, i’m now running into the youtube ‘quotaexceeded’ bug. i’ve tried several fixes presented here including unistalling and reinstalling youtube addon as well as deleting xml file from addon and re-authorizing with the start up wizard. can’t seem to get it to work and can’t find a workable fix here. though i admit there is a lot of stuff here and i may have missed the solution. if i could get a pointer to a solution i’d be eternally greatful. thanks
