Built-In VPN Does Not Work By Default When Opening Firefox

The free native VPN stays enabled when I launch Firefox at the start of every day after turning on my Desktop PC, but the problem is that despite the VPN itself being 'on', it's not actually 'on'. To make the actual VPN work I need to turn the VPN 'off' and then turn the VPN back 'on' again. I know for a fact that the VPN doesn't instantly work at launch by default because I use the VPN to bypass the age verification popup message on https://www.reddit.com The age verification popup message appears on Reddit when the VPN is claimed to be 'on'. So like I said, when I turn the VPN 'off' and then back 'on' this makes the VPN actually work like normal. It's annoying having to switch the VPN 'off' and then back 'on' every time I fire up Firefox to the foreground for the first time. Can this bug be fixed?
