Why doesn't my mobile data work since I upgraded to Marshmallow?

[AC Question]

I have an HTC one M8, and Mobile Data says "Disconnected". I have tried restarting. It worked fine yesterday before the update.

Maybe the Apn Got deleted ,Try to add your carries apn again that should help , What carrier do you use?

Same happened to me, everything is working fine but Mobile data shows as " disconnected" and I tried selecting the APN again and resetting the default one but nothing worked, can anyone help us to resolve this issue.

Did you get it fixed?

I really have no idea. I thought about the APN too but it seems like it is not the issue..
