Hey there. I know this thread is quite old, but I'd like to share my advice if someone is still looking for help with using VPN. So, as long as you have a good internet connection, your VPN should work just fine on any device. However, if you're looking for a more stable solution, you might want to check out a VPS. A VPS is like a virtual machine that you can use to host your own VPN. This way, you can access your VPN from any device, anywhere in the world! If you're interested, I found a website that has some cool VPS options at a good price. Check it out here:
