I found a similar issue on this topic SDKAuth() does not trigger authcb
There is mentioned that sdk folder was corrupted. So I removed existed one from my project and did copy from original repo. It fixed the problem. authcallback is triggered.
But now the original demo application doesn’t work. I dug deeper and realized that there are used simlinks to some resources. So when I copied resources from original zoom-sdk-electron folder to my project simlincs was changed… Is it possible?
If here is someone who is an expert in unix soft/hard links your help is welcome!
