Issue Summary

Changes made on iOS are occasionally not reflected on web/server.

Under certain conditions, the Trello iOS app's sync queue becomes unresponsive, displaying errors that prevent changes made on iOS from being reflected on Trello's web or server.

Steps to Reproduce

The issue is not consistently reproducible. Users may notice an item in the sync queue with a red error. When that item is deleted from the queue, other items in the queue should sync without error.

Expected Results

Once a change is made on a card in the iOS app, it should be immediately pushed and reflected in Trello on all platforms.

Actual Results

Once the iOS app receives an error, this item and all actions that happen after it don't get synced, either.

Workaround

Deleting the stuck item in the Sync queue on iOS should allow the app to sync again
