YouTube and marshmallows don't work

[Altamimi7]

I just upgraded my M4 aqua to Android 6.0.1, now YouTube app gets deleted when ever I restart the phone, why, ?

Hi @Altamimi7,

Welcome to the community.

That's strange. Does the app itself get removed from the phone? Can you see it under Settings > Apps? Or is the shortcut for it removed from your homescreen?

[Altamimi7]

The shortcut and the whole app gets uninstalled, I can't see it under setting, till I reinstall it again, I have reinstall it more than 10 times now. The phone is better with 6.0.1 faster smooth, but YouTube app gets deleted when I restart it

@Altamimi7

Are you moving the app to the SD card? wasn't youtube preloaded with your device?

@Altamimi7,

If you start your phone in safe mode, is YouTube missing from there too?

[Altamimi7]

You can't move YouTube to SD card, trust me I tried and failed to do so, yes my was pretty loaded with all Google Apps including YouTube, but this started after I upgraded from lollipop to marshmallows, 3 days ago

@Altamimi7,

Have you been able to test it in safe mode yet?

[Altamimi7]

I have not tested in a safe mode yet, how to do so? Thanks

I have completely the same issue. This is unacceptable.
I have run save mode with no result.
The most frustrating is that Sony doesn't even noticed this bug. So apart of the storage issue (I have to delete fb app to make any app installation), i have now to reinstall the YouTube app every time my phone turns off due to battery. After that I have to follow from the beginning all the process with uninstall and install apps.
Congratulations Sony
