Cannot compile under Catalina

Creating app and . running them works great but when I try to compile It ask me to buy a license. I am logged in on my account and I can see my license

Oh, very good. I’ve had this problem since the very first beta. Support told me that I was the only one to have this problem.

Do you have 2 computers, too? I can run/build on my High Sierra machine. Running is good on Catalina. As soon as I do a build I lose the license.

Please contact support and tell them about your compile problem. Seems to be Catalina only.

Yes I have another High Sierra Mac that work fine, will send info to support, Thanks for the input
