User blog comment:EpicAlexisMaxwell/Tabber doesn't work on Android. SMH :(/@comment-44807868-20200921132300

Tabbers have never worked on mobile skin; see Help:Tabber. Its use is also not highly recommendable in general as explained on User blog:FishTank/Short and long pages on Fandom. You can to offer your feedback about how it functions on mobile if you want, but I personally wouldn't count on it and certainly not on an ultimatum either.
