I got this message after I try to validate the app. I was trying to validate it first before uploading to ituneconnect. Is there issue with the server being busy?
Unable to process app at this time due to a general error
Not unusual. Best to be patient and keep trying.
Note the next scheduled services downtime is for April 22, beginning at 7:00 a.m. (PDT)
"Unable to process app at this time due to a general error" is a server bug i think. Especially if you are trying to validate it appears after a while. On the other hand, if you try to upload your application, mostly it stucks at 90% or done without error. It is very weird.
