HTC One M7 GPE won't update from Jellybean

I have an HTC One M7 Google Play Edition running Jellybean (4.2.2). This lags well behind the current version of android for this version of the phone. Unfortunately, I am unable to receive an OTA update (everytime I check, I get a message stating that my phone is up to date). Is there anything I can do to force an OTA update short of rooting the device and manually installing the updates? I am currently on a BYOD plan with T-Mobile if that matters at all.
