Cannot submit a new build

Error Domain=ITunesConnectionAuthenticationErrorDomain Code=-26000

Attempting to submit a new build continually failing and I suspect this is due to some issues on Apple's servers (Status code: 502, Bad Gateway)

Anyone else seeing this issue? Apple's status page doesn't show any open incidents.

Having issues submitting to testflight. Also app store connect is loading very slowly on all browsers and networks I have tried? Wonder if there is an outage

Looks like Expo opened an incident on their end due to high fail % of app build submissions
