Yup - saves me when I have intermittent problems with plugin.video.youtube
I can hop over to Flatpak'ed VacuumTube, then back to Kodi without having to mess around with the 'official' Youtube apps on Amazon Firestick (Oh... my ... god ... the UI's advert spam is so obnoxious) or the TV (Oh ... my ... god ... the UI is *painfully* slow. Oh - also obnoxious advert spam)
Yeah, VacuumTube is awesome, both on Pi4/5 & with Generic on Intel boards.
