In our service, we have integrated the functionality of working with Instagram business accounts by obtaining data from the user's Facebook business pages. That is, we retrieve data about the user's Facebook pages, and then we obtain information about Instagram business accounts linked to those pages. This week, we encountered an issue where we are unable to access all of the user's Facebook pages, but only a portion of them. For example, the user has 4 pages, two of which are linked to Instagram business accounts. Using the API method /me/accounts, we can retrieve data about the user's pages and the linked Instagram business accounts. However, out of the 4 pages, we only receive data for part of them (2 pages), and we cannot access the pages associated with Instagram business accounts.

We have tried enabling different permissions, but this did not help. The issue appeared this week, whereas everything was working fine before. We kindly ask for your assistance in investigating this issue and providing information on possible causes and ways to resolve it.

Thank you in advance for your help!
