Does not work in views when using relationships

Try testing with the geo field. are you try with geo without relationship? Anyway, the geo field doesn't show anything in Google Calendar, Outlook or Thunder Bird, it works on iPhone. test on my own it show apple map on iphone calendar.

I believe that this issue is related to the first one I raised: https://www.drupal.org/project/date_ical/issues/3415703#comment-15408503 🐛 Geolocation fields not working Active

At first I thought it was the Geolocation fields not working but this issue supersedes it and I believe that the wider issue is that fields which use relationships are not working. If we can ignore the Geofield for a second, no fields which use relationships work.

So for example, I have a content type of "Location" which references "Event" nodes. The events are in a view displayed as a table and also have an attached iCal feed. The addresses and names of the locations are loaded into the events table using the relationship based on the entity reference field. They show fine in the table, but the fields are not working on the iCal feed. I have also triad adding them into the body field by rewriting it but they are not showing.

does it work without relationship?

That's correct - To test for you I added an address field to the "Events" content type and added an address to one of them and then the location was present in the iCal feed for that particular event.

Addresses on related entities are still not showing / being detected on the iCal view. Addresses on the event entities are showing but the issue here is that the address fields on related entities are not showing.

It works on my local, but you can try with a global custom text field and override the text
