Cannot Connect to LTE or 4G after Nougat Update

[Xander0103]

I have recently updated my Sony Xperia XA Ultra Dual Sim to Android 7.0 Nougat. I have noticed that I am unable to connect to LTE or even 4G. I made sure that I am on a 4G/LTE site and my Sim is 4G/LTE compatible. Can you help me fix this?

Go to Settings -> More -> Mobile networks -> Preferred network type -> set to "LTE (preferred)/WCDMA/GSM"

If it's already set to this option, set to a different option and then back to LTE option.

I have the same problem. SONY please give a solution to this. 

Before Nougat, Im playing online with 2 bars of LTE and im not having any problems with XPERIA XA ULTRA. 

After upgrading to Nougat, I changed to 3G because I cant be contact in LTE, but switching back to LTE/4G, it cant be selected anymore, I mean its there but it doesnt switch to 4G.

Does SONY even read this?

Transfer your sim to the other sim slat and refresh your phone. Try to select LTE.

Same problem for me. I have tried changing the settings back and forth in

Settings -> More -> Mobile networks -> Preferred network type ->

but it never connects to LTE even if I have selected LTE as preferred.

I have also done a factory reset, but problem remains. The problem is serious since at my home LTE is the only available network in the air, i.e. I can not call and no one can call me when I'm at home.... I'm, not very impressed...
