Due to recent changes that Twitter has made which have affected our app, it's now required to refresh your Twitter account connections to ensure your posts do not fail.
You can do this from the accounts page here https://app.threadcreator.com/dashboard/settings/accounts or by simply logging in to thread creator as your Twitter account.
We're sorry about the issues over the last few weeks, with the switch of ownership it's brought on some issues, which are mostly resolved now.
We're committed to building the #1 Twitter scheduling platform, and will do everything we can to make it work as smoothly as possible.
