I use the ESP-IDE.Thank you so much! I'll give it a try this weekend.
As far as I understand, you can compile it and it works? Which wifi-manager repo and which compiling environment are you using? I tried VSCode, ESP-IDE, ElcipseIDE but no luck...

Attached my file. This you can compile and flash.
But the wifi manager is a bit bugy. i have to try it some times to join to my network.
Good Luck.
