[MCPE-33009] Global resource packs have to be reapplied after restarting the game (Resource Packs NOT saving from game)

Update on this issue by [Mojang] Mega_Spud (Jay Wells):

This bug has been reported to our internal bug tracker for further testing and a fix. It is scheduled to be fixed in one of the future updates (no specific date can be provided).

While we understand your frustration at certain game feature or mechanics not working as you would always like or expect, please remember that there is not always a simple fix that will resolve the issue immediately. Please be assured we are actively looking into a solution though.

Since Betas, resource packs are not saving from game data or it just doesn't apply when restarting the game, as a resource pack maker this is very annoying because of the fact that you have to refresh resource packs by inserting them again
