TBA strings are coming from a different branch each release, which makes it difficult to track in transifex
Most of the resources we have in Transifex are linked to source files we have on our own repositories, so when we make changes on our repositories, those changes appear automatically in Transifex. This happens with all Torbutton strings, coming mostly from the torbutton.git repository.
But the strings for Tor Browser for Android come from the Tor Browser repository, and the branch name is not 'master' but it is the release name, as in current branch is 'tor-browser-60.6.1esr-8.5-1'
This makes it impossible to track permanently the branch, somebody needs to login to transifex with enough privileges to change the autoupdate to the new URL, or do updates as part of the release cycle with the push feature of the tx client ( https://docs.transifex.com/client/push )
