Gmail sync issues.....

Anyone else having issues these past few days with their desktop Gmail inbox not showing as read, when you've already read it on your Nexus 6?

I just started having these issues and have no idea what caused them. I'm rooted and unlocked, running stock 5.1.1 LVY48F, Verizon

I've never had this problem before. I'm thinking it's connected to the fact I just pushed the stagefright update to LVY48F this past weekend.

I've checked settings and everything, no idea how to fix this.

Thanks-
