I've mentioned this elsewhere, but I thought it might be worth creating a topic here.
In the CIQ bug reports forum, if you leave a comment that contains a bare URL (url as plain text), under some circumstances, the url will be abbreviated, but not converted into a clickable link (meaning the full URL will be lost).
This problem is exacerbated by the fact that comments can't be edited in the bug reports forum.
I can't reproduce this reliably, but I've seen it happen before.
I've seen an even worse variant where the URL is completely wiped out, as well as a portion of text following the URL. I think one way to make it happen (not reliably) is to surround a bare url with square brackets. (This is something I've done in the non-bug reports forums to *prevent* url abbreviation from occurring).
e.g. the following content is fine is this forum, but would likely cause issues in the bug reports forums: [https://forums.garmin.com/developer/connect-iq/f/forum-about-the-forum/404407/bare-url-text-abbreviated-but-not-converted-into-a-link-in-the-ciq-bug-reports-forum-resulting-in-the-loss-of-the-original-url/]
