When I try to hit

https://graph.facebook.com/me?access_token={{token}} 

using the access token generated from flutter facebook auth on IOS it returns error

{     "error": {         "message": "Invalid OAuth access token - Cannot parse access token",         "type": "OAuthException",         "code": 190,         "fbtrace_id": "A7VLOSLTiXhbqehRbUpNz7z"     } } 

however when I try to generate token from android device and use it in the same endpoint it works fine.

I downgraded flutter facebook auth and same issue still occurs

I have been using ngrok for local testing for quite some time now with no problem at all. But recently, when I set my webhook in my app's callback url, it says:

The callback URL or verify token couldn't be validated. Please verify the provided information or try again later.

The url and token is correct, the endpoint does not get hit when I am doing it from Meta. When I use postman to make a GET request to that same url, I can see the request on ngrok terminal and the vscode terminal too. But not when I am verifying it on Meta. Is Meta now allowing requests to ngrok? What can I do to avoid this?

At midnight UTC on the 7th of June my facebook integration started returning:

((#100) This endpoint requires the 'pages_read_engagement' permission or the 'Page Public Content Access' feature.

When getting information about a page.

I can't see anything on the changelogs about something on this date, but I had a notice of deprecation of v13 for the 28th of May and the switch to v14.

Maybe this change was rolled out over time and my account got the change on the 7th of June? I can't see anything relevant in the v14 changelog.

I am lost on what the issue is.

The Page token I am testing has 'pages_read_engagement' in its scope and my app also has 'Page Public Content Access'.

My own facebook page works though but users pages that appear to have the right permissions don't.

Is there an automated way to delete all my page's comments with Graph API (or other dev tool) without using an IDE?

enter image description here

I use /adcreatives to create such a post on the page. But to appear on the page, it requires payment setup.

I want to create a post on the page with a like page button like the picture. no need to advertise, can anyone help me?
