RUTX50 and current (stable) Firmware, SIM-PIN issues?

Hi,
since upgrade to current RUTX_R_00.07.21.3 I have some strange SIM-PIN-issues.

Privious versions (including last stable 7.20.3) worked fine - without any problems … for a very long, long time.
Since the update to the current version, after every reconnect the GUI asks for the PIN (via WebGUI - Status - Overview), although the PIN is saved under WebGUI - Network - Mobile - General (for SIM1).

MNO is T-Mobile Germany.

Kind regards,

Philipp

I have some new information.
Neighter upgrading to 7.22 nor downgrading to 7.20 solves the issue.

Possible Solution

I just wanted to write down the PINs from my config in the WebUI for downgrading because of another issue, and the PINs shown there are 1111 for both SIMs, which are definitely not the PINs I set…
