Hi there,
There are two bugs, that trouble my mind:
First: My Facebook-App stopped working.
Second: The login via FB works on desktop machines without troubles. On mobile devices it stops redirecting to the correct site and remains on this link:

Sure, you can help,

Hey Peter,

It seems like I can able to login via Facebook in my device, unable to replicate that issue what you described at your first post.

This is what i tested so far :

Android
- Chrome app - work fine
- Firefox app - work fine

iPhone
- Chrome app - work fine
- Safari app - work fine
- Firefox app - unable to click that Facebook button

May i know which device and which browser you tested on this?

Is it possible for you record a video for this so we can better have a look?

Good morning Arlex,
i use a HUAWEI P9. Here is a video about.
One of my user told, he's unable to login anyway (using an IPhone, but i don't know which browser).
Excuse my early-morning english in the video.

I've tested on Huawei device, it seems like it did automatically redirect back to the first tab, you can watch my attached that video.

Based on what i see, your one got one extra step pop up ask you choose facebook or chrome.

May i know is there a way to get rid of this step and see whether that issue still persist.

By the way, can you consult with your client which browser app he trying to login on your site and what happen when click on the Facebook button.

My phone does an extra step, you're right. But this behavior is new. I installed firefox now to check that on a different browser and here it works (no extra step). I have really no idea, why chrome is doing that.
Btw. because we are currently with the social logins, twitter login has a problem with the token (attachment #1) I regenerated that token on twitters app management site, but that had no affect.
LinkedIn works
Finally to the missing autopost app. Can this be due to missing reviews by Facebook or any changes in there permissions last time?
greetings and still thanks for your time
Peter

Yes, recently we also get number of our user reported this Twitter login issue as well.

Based on what i found out is, it seems like Twitter already announced this last month https://twittercommunity.com/t/action-required-sign-in-with-twitter-users-must-whitelist-callback-urls/105342 , now Twitter will forced all the app MUST be set that correct callback URL.

It seems like I was unable to connect with your FTP server.

Can you follow my guideline here and see how it goes?

Finally to the missing autopost app. Can this be due to missing reviews by Facebook or any changes in there permissions last time?

You're most welcome.

I already help you selected Scopes Permission for publish_action from your site backend, that autopost option will be appear on the story form.

If Facebook already approval your user permission, the user can able to use this permission until August 1, 2018 , because Facebook already updated their API and this user permission will be deprecated.

You can read more on their blog post https://developers.facebook.com/blog/post/2018/04/24/new-facebook-platform-product-changes-policy-updates/

After August 1, 2018, you have to un-select this user permission publish_action from your backend setting, you can refer on my attached screenshot below.
