Twitter links are no longer showing up in Mattermost with a Preview box.
Steps to reproduce
Post a link to a tweet in v5.2.4
Twitter links have a Preview box.
We upgraded to Mattermost v5.2.4 four days ago. Twitter link previews were working fine two days, on Monday. Yesterday, on Tuesday, they mysteriously stopped working and I have not been able to find the problem.
Twitter links still work in Slack and in iMessage, so I don’t believe Twitter is the problem. Previews for Facebook, YouTube and random news articles still work fine in Mattermost. I’ve looked in System Console and “Enable Link Previews” is flagged as True, as well as “Website Link Previews” in in my personal Account Settings.
Any help would be appreciated. Thank you.
