Double SIM don't work

I really like the principle of /e/, everything suits me on my Pocophone F1.

I have two problems, the first is very important to me, the dual sim function does not work! It’s a real problem.
The second is Vinted which doesn’t work either, but I can do without it.

Is there any solution for that?
