This started all of a sudden. Other APIs e.g. Campaign creation, Adset creation etc are working fine but I am not able to create ads via API.
Error-
{ "error": { "message": "Application does not have permission for this action", "type": "OAuthException", "code": 10, "error_subcode": 1815574, "is_transient": false, "error_user_title": "App Permission Missing", "error_user_msg": "App 729,690,972,144,381 does not have permission for this action", "fbtrace_id": "Av2JIOM0448H4j4046cSstT" } }

Some batch calls updating catalog products fail with following error:
Locality fields are missing or incomplete: Your feed is missing locality information. Check to make sure you include: availability_circle_origin and availability_circle_radius, or availability_polygon_coordinates, or availability_postal_codes, or availability_circle_radius and address
However, I can't find any document describing those fields: - availability_circle_origin - availability_circle_radius - availability_polygon_coordinates - availability_postal_codes - availability_circle_radius and address
If anybody knows any documents about those fields, could you share them? I can't find any clue to resolve the problem.

I am reaching out to report an issue that I've been experiencing for almost a month now since I changed my Facebook Pixel. Following the change, all the audiences created from events such as Add to Cart, Purchase, and View Content are not functioning correctly. Specifically, I keep receiving the message "Size temporarily unavailable. The type of data your pixel collects has recently changed. You can expect your audience size to become available again within 2 days of that change." However, it's been significantly longer than 2 days, and the problem persists.
This issue is impacting my ability to effectively target and retarget my ads, leading to a potential decrease in my campaign's performance. I have attempted to troubleshoot this problem on my end to no avail.
Could you please assist me in resolving this issue? Any guidance on steps I should take or any adjustments on your end would be greatly appreciated. I look forward to your prompt response and am eager to resolve this issue as soon as possible.
Thank you for your attention to this matter.

Hello! Our app is granted access to clients’ pages and ad accounts to do advertising on their behalf via the marketing API. More recently, a user has had a problem with his access to an ad account. We use the {user-id}/adaccounts endpoint to check the user’s access to an ad account (specifically the user_tasks field). For this user, the user tasks are not returned for a specific ad account. The reason this is problematic for us is because from evidence provided by the user, he has been added to the business as a basic access user, to manage the ad account {ad-account-id} as an asset with FULL permission (i.e. MANAGE & including all the partial user tasks as well). This user is an anomaly since he is the only one with such a problem, and there is no clear indication as to why the API says he doesn’t have tasks on the ad account whereas the business manager says otherwise. Thank you for your help!
