Thanks guys for the feedback !
Unfortunately, we have little to no control on how Tapatalk fetches information from our board to push notifications in the app.
Of course we could tinker into their code to see what's wrong, but that would most likely prevent the plugin from working, in addition of being a breach of their rules.
We will not forget this tapatalk issue, but in the meantime, I'll be working on fixing the mobile version of the board, so that Tapatalk isn't really needed in the end
Cheers
