In Meta Developer, our WhatsApp app doesn't show anything—it displays a blank page and doesn't show the API setup and configuration. We've been experiencing this issue for 5 days.

I've been trying to access the Quickstart, API setup, and configuration menu in my WhatsApp Business app for some time now and all I get is a blank screen (attached). I've tried to remove cache and cookies, and I've also redone an account from scratch but the problem persists. It's been 4 days. How to solve this problem?

Regarding Meta Ads API action_attribution_windows parameter, what is the window for skan_click and skan_view? Is it same as default 7-day click-through and 1-day view-through? In the reporting tool, the SKAN attribution only showed value for skan_click, but when using API to get skan_click and skan_view, there are values for both. Why is skan_view ommited in Meta Ads reporting tool? Thanks.

From yesterday onwards In meta developer dashboard WhatsApp API Setup and configuration page is showing blank screen please check the attached screenshot

I am trying to set up a facebook messenger chatbot using dialogflow, and when I am trying to integrate both the services, I get this error message

com.google.dialogflow.bots.common.exceptions.BotWasNotStartedException: Code 400: (#100) You must set a Get Started button if you also wish to use persistent menu.

I tried the method referred in this question : get started button for fb messenger in dialog flow (get started button for fb messenger in dialog flow)

but it threw the error when I tried sending a POST request as given in the answer : "error": {"message": "(#100) Requires one of the params: get_started,persistent_menu,target_audience,whitelisted_domains,greeting,account_linking_url,payment_settings,home_url,ice_breakers,platform,title,description,commands", What do I do and how do I proceed from here? Is there a PHP or a JSON code that I must integrate? Or is there something else I can do about it?
