Cannot change connection type in app
I am connecting to my Archer A7 router (note: NOT the Archer A10) through the Tether app. I live in Peru, South America. I have need of changing from Dynamic IP to L2TP (for VPN connection). I used to be able to do this through the app under "Internet Connection" -> "Connection Type", but recently that has changed and will not allow me to tap on "Connection Type " to change and save the changes.
I can change it via the web browser, but before I could on the Android app and it was much more convenient.
Any help would be greatly appreciated!
