since a couple of weeks, I've got the problem that I'm unable to sign in to the App Store Connect App on my iPhone. The error message says
"The certificate for this server is invalid. You might be connecting to a server that is pretending to be "itcmobile.itunes.apple.com" which could put your confidential information at risk".
I don't have any problems logging in to app store connect via the Safari browser on my mac.
I hope anybody could tell me what is causing the problem. Thank you very much.
Can someone from Apple please respond to this? I'm having the same issue, and it's four months later.
When I encounter the same issue, find my Apple connect App is old version. When updating to the latest one, the problem is fixed.
You could try when using Connect App.
