LtAP mini SIM slot

Hello.

I am using an LtAP mini with SIM card and not always but sometimes it changes the sim slot to “down” when it was configured as “up”.

I need to change it again at it works but it changes by itself, mostly when I reboot it or shut down and power on again.

Any of you knows if it is a known issue or i am the only one facing it.

It can’t happen as it stores the configuration of the slot.
The change happens after the reboot?
Can you easy reproduce it?

Yes.

I only need to power on and off the device several times.
