Quick note:

I just logged in to my service record to take photos to show the comparison. Here they are:

I noticed this morning that 2 achievments did change on my service record. The "A for Effort" and "Extra Credit" which were both completed but had not popped because of the common glitch. I set the clock back yesterday to 2014 and completed a weekly challenge and they popped, so there must be some communication between the phone and game server.
