Very slow code response or response stopped

Hello,
I made the pro payment, but it’s still too slow to use. It’s worse than just using the free GPT version. What’s the problem?
If this issue isn’t resolved, I would like to request a refund.

thanks.

Which model are you using and do you use a VPN or Zscaler?

I am using claude 3.5 sonnet, but is it the same for other models as well. I do not use a vpn or zcaler. It stops after printing just a few lines of code.
