Can not connect to network

[orlapalm]

Hello, I have noticed that some app can not connect to network, but the permissions is not asked when it is installed. Is it a A12 behaviour or just an issue on this release? If I look for in permissions, I not found how enable this? I have a POCO F3 with 10-27 release
Thanks in advance

I have a similar phone but never had such a problem, I believe you should update the OS and the security patch - latest.
I used 5 to 6 different vpn apps and only of them don't ask permission but the rest works fine. I think the one that doesn't ask is that it's a reseller vpn rather normal a vpn.
