I’d like to give this issue a push. Namely because it is still not mentioned in the upcoming features (Upcoming Features (updated 4/28/25))
The only announcement is “Improve indexing while not on Wi-Fi”, which won’t help the problem with GDrive.
However, so far i had no quota bans. And i’m not sure why. Currently i got 12TB in my Google Drive Account aka 7385 files in total.
First question: Is this still too little to get a quota ban? Secondly, so far i’m only watching on my iPhone (but ATV soon, too) using the
Files tab instead the library tab. And from this point i go through the folders to the film/series i want. The films folder (679 files) loads in like 6 seconds,
the series folder (6027) needs 100 seconds. A little trick to cut this down: Currently i’m watching Friends (236 episodes +236 .srt files), i favored folder
Friends in Series/Friends/, so now it only takes 7 seconds to open it and show me the thumbnails etc from all the 10 seasons.
Hence the question: Is that the reason why i don’t get the quota bans? Cause i never use the library to scan the whole thing everytime, instead i only access one special folder path.
Nonetheless, i hope for a performance fix in scanning Google Drive! When it’s not about just bingwatching one series at a time and instead i wanna scroll through my whole collection, it would be a pain in the ass to wait for the metadata every time. Especially because my GDrive gets bigger everyday.. 
Hopefully a developer takes a look at this, greetings!
