iTunes connect error "To use this application, you must first sign in to iTunes Connect and sign the relevant contracts."

Question

I try to sign in the application loader, and it comes out the error message said "To use this application, you must first sign in to Itunes Connect and sign the relevant contracts", and I did sign for the relevant contracts under Itunes Connect > Agreements, Tax and Banking, however I still not manage to sign in.

Answer 1

Don't try to launch Application Loader from Finder or desktop. Juste open it from Xcode (since last update) : Xcode => Open Developer Tool.

There you'll be asked to accept some terms (prob due to new GDPR or whatever) not from itunes connect as they WRONGLY prompt you ...
