NEXS2GO/EM9191 Band Scanning & Locking

[Rgamer84]

I have a NEXS2GO running the latest GoldenOrb_2022-04-09 version with an EM9191 in a sled. I'm having some issues finding good information and also believe I'm hitting a few quirks in the current version.

1. When I use the band scanner, it doesn't find towers that I'd expect to see, even the ones it's currently connected to. The LTE/NR bands do not show up in the list when done scanning.
2. I have been unable to find anything on doing a bandlock on 5G bands. Currently I'm on B66@20MHz/n41@100MHz. I can figure out the AT commands for B66 however how do you bandlock for n41?
3. When I try to change the Cellular Mode to 5G Only (SA Mode) it continually goes back to Automatic. It doesn't seem to matter what I select, it always says the Current Cellular Mode is Automatic.

I suspect that maybe GoldenOrb isn't fully baked for 5G and the EM9191 and that is why I'm seeing these oddities but figured I should 1) report them and 2) see if anyone knows a workaround.
