Bug description

I cannot share iCalendar (.ics) files into Signal via the share sheet. I receive an error message.

I don't know how long this has been happening but I do not think it is new.

I can, however, share them within the app. This suggests to me that it is an issue specific to the share sheet.

Steps to reproduce

1. Open an iCalendar file.
2. Share it into Signal via the share sheet.

I built a very simple proof-of-concept on the web. Visit this page on your iPhone. Click the link and try to share the event into Signal.

Actual result: An error message appears.

Expected result: I can successfully share the file.

Setup:
