Speed drops to 20mbps from 1000mbps with Warp+

I am currently having issues with warp+. It currently gets 20 mbps when I turn it on. It used to be around 600-700mbps. I thought not having a license caused this so I bought warp+ and activated it with warp-cli registration license ... cli command. Did not change anything. I live in Turkey and I think the cause is the servers over here. Is there a way to find the best servers available?
