My issue might be related to yours.
We are using the same BAS program and the same proxies.
When I automate a website from my own PC and ISP (in Poland), everything works perfectly.
However, when I give the exact same project to a person in Russia, he faces issues. On one of his computers (using mobile internet), it doesn't work at all. On his other computer, it works to some extent, but the detection rate is very high.
This is all happening with the literally the same project and the same proxies.
