I have discovered that there is a hidden "Add" button on the left of the "Delete" button; in that area, the backgound color should be white, instead it is cyan.
Tested with Mozilla Firefox and Google Chrome.
Current firmware version: 1.1.0 0.9.1 v0001.0 Build 201204 Rel.66940n (this does not happen with the stable version 1.2.0 0.9.1 v0001.0 Build 200511 Rel.44954n).
(In Italian, "Riserva Indirizzi = Address Reservation", "Elimina" = "Delete").

Please also confirm the current firmware version of the MR600, thanks.

Can you please assist with getting the Beta firmware for the MR200 (V3/V4) fixed so we can manually select Band 41?
Currently, there is a bug that will not allow Band 41 selection, but all other options work OK.
Causing us alot of issues as we need to use Band 41 :(
Below is screen shot of the error when you try to select band 41.
Please help, thanks, Hayden

Hello, are you on the latest beta firmware we provided on this thread?
Who is the SIM card provider, please? Could you please check the network type and band supported by your SIM card provider? If you cannot choose band 41, I'm afraid it is not supported.

Hi @Kevin_Z,
Yes I tried the beta firmware: (Archer MR200(EU)_V3/V4, Archer MR400(EU)_V2/V3, TL-MR6400(EU)_V3/V4, TL-MR150(EU)_V1: LTE_GATEWAYv3_1.11.0_0.9.1_up_boot(200325)_2020-06-12_15.48.55.zip), this is not a SIM or Provider issue, this is a bug in the beta firmware affecting MR200 V4.
It will connect to Band 41 sometimes when left on default the "All Bands", but it also moves to Band 3 which has much worse signal in my area.
This is why I need the Band 41 lock to work properly. I tested same SIM card & provider in MR6400 V3 with Beta firmware, Band41 lock works as expected and connects no problem. This just seems to affect Band 41 lock only on the MR200 V4 wiith Beta firmware.
Please ask your engineers to check. Thanks, Hayden
