I've installed latest stable release on my CC9e. Before, I was using an app called "Every Proxy" to share my VPN connection over the hotspot. Basically opening a HTTP or SOCKS proxy on the phone allowed the VPN to be tethered without the need for root and system hacks. On xiaomi.eu ROM, however, this doesn't work. Opening a proxy by itself works fine but after connecting to the VPN laptop suddenly drops the connection. I already rolled back to China ROM because this feature is essential for me.
Never mind. It's an issue with android 10 sorry for the confusion.
