Tl;DR

Client is fucking idiot

Longer version:

So im creating an apinfornclient, he integrated everything went smoothly, than he requested update changing few things. He also told me before to not change api without him knowing. So I deployed on test. Subdomain clone with updates.

After iver week waiting for his response was "okay but how do I look at starts etc, where is dashboard"

I calmly reply

"Did you tried https://test.example.com ?"

"Ok it works"

Seriosuly.... Why they didnt even attempt to use brain on this ;-;
