when we schedule a post with Photo using put_photo is getting scheduled but not visible in content tab in Meta Business Suite

Screenshot attached, I have the IG account selected that I want to add a tester account to, but it simply shows "Form can't be saved". There doesn't appear to be anything not correctly selected.
Any help here is greatly appreciated, thanks!

Hello everyone, I'm trying to simply add a tester for my Instagram account unfortunantly it's not letting me it's returning a weird error Form can't be saved Please verify all information is entered correctly and try again|
would you please help me figure this out ?

When I request for an IG users media_count, it will return the following error:
{
"error": {
"code": 1,
"message": "Please reduce the amount of data you're asking for, then retry your request"
}
}
This seems incorrect since I am only requesting a single field value. The user does have over 12K posts, but if I am unable to use this query value, what should I use?
Query: {ID}?fields=media_count

Hey, we use Facebook Login for our website. Facebook spotted an issue which got fixed but I believe what has happened is that we forgot to get back to Facebook and ask them to re-test it and now they have just gone and disabled our account.
Is there any way to speed up the process of re-enabling the account? Starting to feel like enabling facebook login at all was a mistake if they just go and turn it off without any direct way to get it re-enabled for us, users not being able to access our product is quite problematic.
