Question description

My yt works without spoof client (i use revanced gms core, with other gms core i have buffering). In rvx chat i met a few people who also have working yt without spoof but with another gms core (seem like gms core version individual for everyone(?)

All other chatters must turn on spoof client to fix buffering issue anyway. I tried to get at least a little logic there but cant.

From what it depend? Or this is really full randomized thing and we just lucky?

Or yes is there any hope to put away side effect of spoof client, or spoof client at all in future for everyone?
Its maybe biggest question which i try to undertand 2 month

Starting in 2023, Android YouTube clients will require a valid PoToken to play videos.
Because this is a server-side change, all clients that use the YouTube API are affected.
(Other open source YouTube clients besides ReVanced are also affected.)

In other words, if GmsCore's DroidGuard's VM (com.google.ccc.abuse.droidguard.DroidGuard) does not generate the correct DroidGuardResult, users will experience playback issues.

Fortunately, microg/GmsCore implemented PoTokenService on December 22, 2023, and the playback issue was resolved by ReVanced Team releasing ReVanced/GmsCore fork on March 26, 2024.

GmsCore's DroidGuard's VM (com.google.ccc.abuse.droidguard.DroidGuard) is updated approximately every two weeks by Google servers.

The current GmsCore does not support the new DroidGuard VM, so if users reinstall GmsCore after June 2024, they will experience playback issues.

If users installed GmsCore between March 2024 and June 2024 and have never uninstalled it, they will not experience playback issues.

In this case, the user must spoof the client to bypass the playback issue.

※ Exceptionally, there are no playback issues without spoofing the client in the following cases:

1. User restored data from a DroidGuard VM generated between March 2024 and June 2024 using ADB.
2. Although the user installed GmsCore after June 2024, the DroidGuard VM was not updated due to a server-side issue, so valid DroudGuardResults were obtained.

And last one, has it chance to be fixed in the future for all users? Or it impossible to say due unpredictable google's action after all

It seems very unlikely, but if the MicroG Team supports the new DroidGuard VM, the Spoof client patch will not be needed
