Workaround to avoid the error:
Since the checkin failures for this guest are causing a timeout error, the timeline filter can be adjusted to remove these checkins from being displayed and allow faster access to the guest's account. Steps are outlined below.
- Access any guest's timeline in the dashboard.
- Navigate to the timeline filters and uncheck "Checkins"
- Select "Filter."
The checkins have now been removed from displaying on guests' timelines. Now, ou should be able to access the guest's timeline. There will still be a longer load time for this timeline.
