If WipeAway reports that the deletion completed successfully but you can still see events in Google Calendar, this is almost always a display cache issue — not a sign that anything went wrong.
Google Calendar caches event data in your browser and on your devices. When WipeAway deletes events via the Google Calendar API, the deletion is confirmed immediately at the database level — but your Calendar view may not reflect this straight away, because it is still showing cached data.
The deletion did work. If WipeAway showed a completion screen with a final event count, the events have been deleted from Google's servers. The Calendar display just needs to catch up.
If events are still visible after 30 minutes and a full refresh, it is possible that not all events were deleted in the WipeAway session. Sign back into WipeAway, select the same calendar, and run a fresh count. If the count shows remaining events, you can run a follow-up deletion to clear them.
If the count shows 0 events but Calendar still shows them, contact us — this would be an unusual caching behaviour worth investigating.
