Checks on checklists not being saved

Has anyone else started seeing this #bug where some checklist items (in the “Updates” section of pulses) marked as complete (with a check mark) are suddenly not being saved? The appear to work when you check the item off, but when you come back it’s gone.

We’ve confirmed that this is happening across multiple user accounts, on multiple device types/operating systems.

As a team who relies heavily on these checklists for project management, this is a concerning development.
