Old block remains
A period remains unavailable in a platform although the booking was cancelled or removed.
Incorrect blocks
Incorrect blocks often occur when several booking platforms import each other’s iCal calendars. It then becomes unclear which source a block actually came from.
Symptoms
A period remains unavailable in a platform although the booking was cancelled or removed.
You delete a block, but it reappears after the next calendar fetch.
The platform only shows “blocked”, “closed” or “not available”, but not where the period came from.
Solution
kalenderabgleich.de remembers the origin of every imported event. When exporting to a platform, the event that originally came from that platform is left out.
This prevents a platform from receiving its own booking back as an external block through a detour.
