the android version its kinda on a early state but tags work like this: tag1,tag2 or they can be single tags like: tag1
the downloading thing i think it fixes by activating the storage permission
The only problem with that is that there are no permissions, at all.
And I did the same exact tags, "Gay,rating:safe" With and without the quotation marks, and it still did not work
interesting,it must be a godot android version thing ill see if the new update fixes that when i release it
