I was reviewing the release notes for v19, and there are some inconsistencies: 1) It says it was released on January 23, 2023, but I'm pretty sure that's supposed to be 2024 2) It says "In addition, we have deprecated the ability for group admins to install apps on the group, even if they have an admin or developer role on the app." That seems to imply that there will be no more apps for groups, but I can still add an app to my Facebook groups.
Any idea what's going on here?

WHY still issues with the CORS policy, when using the Chat plugin?
Error:

Just to mention, we have tried all the tips from the Help Center. Our site has been whitelisted from the Chat plugin settings etc. Can you give me any help?

In some accounts requesting only media_count for the profile returns: "An unknown error occurred" or "Please reduce the amount of data you're asking for, then retry your request".
This does not happen with all the users, for what i could found it only happens with accounts with a lot of posts like: resiliencia_humana, cabronazi.
Query:
business_discovery.username(resiliencia_humana){media_count}

I'm creating WhatsApp Business Platform API but it return erorr Onboarding Failure Please retry in some time or reach support to get issue fixed.and not creating App.

Adding a new app review request for increased permissions. It's indicating we need to add app to Page Tab or create a new page... We have created the new page but Page/Tab is depricated so can not proceed.
The manual method of creating a link to the page_id and app id no longer works, and using graph api to POST to /{page-id}/tabs is depricated.
What am I missing for being able to submit a review?
