After about a day of use, this stopped working. This morning, I was unable to connect via LTE. If I chose an appropriate APN, it would not stay selected (if I went back into APN's after making a change it would be set to something else).
What I did to fix this was to use APN Backup and Restore to delete all the APN's and then restore ONLY the APN's from the stock ROM. So far, it is working.
