Mobile certificate

Hi.

I wanted to refresh my old phone (LG G5 / Android 8). I did use the « clear credentials/remove all certificates » option.

However now i can’t login into some apps, and almost every website gives me an http warning. Almost no website will work now.

I would like to know how to reinstall those certificates ?

Thank you!

Then, you can retrace the installation steps to re-install the VPN profile/certificates so you can use again:
