Posts Not Saving for WordPress for Showit

I just launched my WordPress blog using Showit. When I try to save, publish, or and images to a post using WordPress on desktop, the save never goes through (it just keeps processing). I can use my mobile app to save and publish posts, but there are limitations to the mobile app, so I can’t use that full-time.

I have tried deactivating plugins and clearing my cache, but neither has worked.
