Been using Feedburner to share content over Twitter via the Socialize feature for a couple of months with no problems, on the 21st May 2019 all my feeds (multiple feeds, several Twitter accounts) stopped posting to Twitter (looks like they all stopped at the same time).
The original feeds and the Feedburner feeds are updating, so the only thing I can see that's wrong is the feed items are not being posted to Twitter.
Have tried reconnecting Feedburner to Twitter multiple times with no joy.
Pl help.
