Does new fire tv stick supports VPN without crashing?

I have a fire tv stick 4K with 1.5gb of ram. I need to use a vpn but it just doesn’t work.

I open the vpn app and activate the connection, then I open another app (for example Netflix) and after a while my vpn disconnects so I need to reopen it again.

I think 1.5gb of ram are not enough so the OS kills the vpn.

I notice the last fire stick had 2gb, will it improve the situation?

TLDR: does someone use a vpn and it actually always work? I need to set it and let it work forever

I use 4K max gen2 and Private Internet Access without issue.

Once you connect it, it is always on. I checked multiple time when I turn on the stick, it was always on automatically.

I use Nord, and the 4K stick and it crashes and reboots constantly

You might change vpn server location to be identical to the Netflix area ?

Do you need to activate it every time or it works even the feature that always keep the vpn on and reconnecting at startup?
