how to add a test user for Instagram? It’s only me who can’t add any of the test users to any application?

I'm trying to generate a token to show my Instagram feed on my website. When trying to create a person for the application, in the Instagram Tester tab, an error appears. I've been trying since yesterday and nothing happens.

Starting sometime between 2024-02-27 02:50 and 2024-02-27 03:35 UTC API started to return followers_count much larger values. whose values are extremely close to fan_count of global page.
for example followers_count for FB_ID = 1579819912230855 jumped from 1 347 052 to 108 741 697
current state https://developers.facebook.com/tools/explorer/186312281379136/?session_id=3470304219947968
other example page Sinsay_PL FB_ID = 100680089286128 followers_count jumped from 52709 to 3 321 884. https://developers.facebook.com/tools/explorer/186312281379136/?session_id=1124552838991325
documentation says followers_count = Number of page followers. fan_count = The number of users who like the Page. For Global Pages this is the count for all Pages across the brand. For New Page Experience Pages, this field will return followers_count.
looks like someone accidentally made it the other way around. followers_count are now equal to fan_count (=fan_global_count)
could you please submit this bug to FB, as i can't :(

Unsupported get request. Object with IDIn the last few hours, we have been experiencing an anomalous increase in the "Unsupported get request. Object with ID" error and the "Code 9007 - Media ID is not available" error.
Can you tell us the reason for this? Is it a temporary problem with the Meta API platform? We have not made any changes to our procedures.
P.S. We are unable to open a bug report in the "report a bug" section.
