FYI: I've had a DTS incident filed since mid-November. Last week I emailed them and they said it was still under investigation and there was no ETA for a fix:(

Thanks @fernandofromcampinas, I'll give Test Flight a try. Although I've had issues with getting Provisioning Profiles to work in my app, but that's a whole different problem. In the meantime, I've been using the workaround that someone (possibly you or @rowlands) mentioned and doing all my Sandbox testing on 10.13.6. It's been working, but my poor 2014 MacBook Pro only has Intel video. So graphics intensive apps... are... running... very... slowly...

OMG. It's working for me on 12.2 as well!

Yup! Working for me on 12.2 also!

Same. Busted here. Again. Maybe we should all start billing Apple for all the lost hours this has been causing us...

I hadn't tried Sandbox testing since it started working for a bunch of you in back mid-May. But I just tried it today with a new app I'm working on and it's DOA. It's the typical "Error fetching receipt for com.blahblah.blah - Error Domain=com.apple.commerce.client Code=500 "(null)" nonsense. Just wondering if anyone else is having the issue again. About to file YA feedback report:-/

It's getting pretty close to 3 days now, so I went ahead and opened a Support Ticket.

Will do:)

@raj_kunvar Sadly not yet. It's now been 8 days since we were able to Notarize any apps. I filed a Dev Support Ticket last week. Apple's automated systems said that someone would get back to me in 1-2 business days. But it's now been over 3 business days without any response from Apple. We're literally stuck and unable to release any apps because of this.

Thanks Quinn:) I just emailed you directly. FWIW, xcrun notarytool history now shows that all the "In Progress" apps are now marked as "Rejected". So it appears that something's happening on Apple's end:)

I was struggling with this very problem. Your code worked perfectly for me. Thanks!

After about 45 minutes Transporter seems like it's back online for me. Weird.
