Seems Facebook mentions have stopped again

[armingrewe]

Haven't had time to check anything (and am on phone only for now), but it looks like Facebook mentions stopped working some time last night. Just as Twitter started to work again...

hey armin! hmm, facebook backfeed is definitely still working for at least some users, eg https://brid.gy/facebook/10206605282077198 and https://brid.gy/facebook/508178999257997 .

what's your bridgy user page?

[armingrewe]

Should be this one for Facebook: https://brid.gy/facebook/776938267

Twitter still works fine, but FB stopped at some point. I know there have been a few likes of the picture I posted this morning, about 8 hours ago. Last one picked up was for yesterday's picture about 22 hours ago.

thanks! agreed, your latest two posts are missing.

suspicious that it stopped working (for you at least) precisely on GDPR day. although the other two working examples are in the EU too, so who knows.

regardless, sorry for the trouble! i'll look into it.

no consistent difference in the FB access token permissions for these accounts.

hey @armingrewe could you try logging into Facebook on https://brid.gy/ again? probably won't fix it, but worth a shot.

[armingrewe]

Sure. Just done, disabled and logged in again. Sadly doesn't seem to have made any difference (so far).

I so wish I could dump Facebook, unfortunately there are so many of my friends on there who won't touch Twitter or G+.

[snarfed]

looks like this is actually affecting everyone after all. the accounts i thought were working, eg https://brid.gy/facebook/10206605282077198 , are actually only getting their own comments and likes, not other people's.

specifically /v2.10/me/feed?... is returning everyone's posts ok, but only their own responses. or maybe only bridgy users'; not sure.

(interestingly https://brid.gy/facebook/508178999257997 is getting everything, but it's a FB page, not a user, which i expect is the difference.)

regardless, i expect the fix is #814...except facebook claims we have until august 1 to resubmit for approval, so i'm not entirely sure this is that.

[snarfed]

i actually now wonder if this is a facebook bug, specifically https://developers.facebook.com/support/bugs/721093238281702/

lots more reports of this there, and FB hasn't yet concluded said it's due to permissions. search for eg comments likes on https://developers.facebook.com/support/bugs/ (the search box under Other Platform Bug Reports, not the top one). eg https://developers.facebook.com/support/bugs/1627371787379210/ .

[armingrewe]

The timing looks about right, they both say it started Thu/Fri if I read it right, which would be the same time as bridgy not getting them any more.

[snarfed]

woo, progress, of a sort. facebook confirmed and said they're investigating.

Thanks for clarifying this. We've managed to repro this problem. We're assigning this to our product team for further investigation.

[snarfed]

sigh. looks like it is permissions after all. another update from FB today:

Sorry for the confusion.

This is intentional and due to the changes we announced here - https://developers.facebook.com/blog/post/2018/05/01/facebook-login-updates-further-protect-privacy/

Specifically:

Additionally, other users' profile information and comments will not be returned when accessing user posts, photos, albums, videos, likes, and reactions unless authorized by those users. These changes are effective immediately for new apps. Apps created before May 1, 2018 will continue to have access to this data until May 24, 2018.

this may mean the end of Facebook backfeed. 😱

[armingrewe]

Very much looks like it. Must admit I don't understand the "unless authorized by those users" part. How would they do that? Can't think of a setting in Facebook to do that.
Well, apparently Generation Z is killing Facebook anyway, so might not be a big loss ;-)
