There is a bug with the Hyperlink format in my Incopy Version 16.4.1 running on Mac OS 12.6.3:
1) I am inserting a Hyperlink in my Incopy document. It is then shown in blue, underlined, Times New Roman. See screenshot.
2) Next I am formatting it as "ohne" Zeichenformat (German) in order to have it in the same format as the other text.
3) I close the file (check in) and open it again (check out).
4) Suddenly, the remainder of the the text is formatted in Hyperlink format. This is a bug.
