Hi ​@Zephyr02 , thanks for flagging this and for sharing your screenshot!

Since this looks like an issue that may require a closer look at your OAuth app setup and the validation warnings you mentioned, I’d recommend reaching out directly to our support team so they can investigate further. You can contact them directly here : Submit a bug report.
Please include the console warnings and a short screen recording if possible, as that will help them troubleshoot more quickly. Thanks for catching this!

Hi ​@Celine_ , thanks for the reply and suggestion. 

I actually figured it out on my own – it was related to 2FA. Once I enabled 2FA on my account, I could publish my app again. 

2FA wasn’t required previously, as I had published a few versions without it. If it is indeed a new requirement I recommend making it more explicit and visible. (Appreciate that new API policies are under way.)

All the best!

Team Zephyr
