The UUID in the ABRP ics export always seems to be "test-1". Since this is a unique identifier, it must be unique for at least every new route. Otherwise, the import of e.g. two different ics-files might fail because the importing calendar program considers it the same appointment (at least Google Calender works that way).
Possible solutions, which might fit for different use cases:
* Use the ABRP plan_uuid for this field
* Use just [Starting Point][DTSTART]
* Use both [Starting Point][DTSTART]-[End Point][DTEND]
Thank you for fixing this!
