URGENT: Anyone else having issues with their phone recognizing fast chargers?

I just upgraded from an S6 Edge to an S6 Edge+ and I've noticed that my phone is having trouble with fast charging. When I plug it in, it simply says "Cable charging". I have to unplug it and plug it back in 3-12 times to get it to say "Fast charging". I'm using the OEM Samsung fast chargers (the one that came with my S6 Edge+ as well as the one that came with my old S6 Edge). My old S6 Edge never had an issue like this.

Is it just my phone, or is this a wide software bug on the new S6 Edge+'s? Trying to determine whether I need to swap my phone at T-Mobile for a new one. Thanks!
