Then they should remember it, I can’t turn the VPN off all the time just for… testing a game and I think I’m not the only one trying to say this.
Anyways, they should also check if some of the content in the PlaySolo thingy is done so that the VPN thinks it may be ‘unsafe’ and stop the process.
So most probably is a problem of both the VPN and Roblox Studio.
If Roblox staff is reading this post please take some notes about this so you can find what the error is.
