Please, if you are using a free VPN, other than ProtonVPN, stop!!! If you need a VPN then pay for it. And don't pick some cheap one with no reputation either. Pick a reputable one.
They are hugely expensive to run and if they are free, run by some unknown, they are getting their profits in ways you won't like.
