"Send a Message" adding prefix to all links

I am having an issue today with the "Send a Message" feature that I have never had before. When I create a hyperlink in my message (adding a link to a video chat for our Sunday School), it automatically adds the prefix https://lcr.churchofjesuschrist.org/ to the beginning of the link. This happens even if I go back and manually edit it—it just automatically adds it back. This is not a huge issue because if I just leave it as plain text then it works fine on the receiving end, but it is an annoying error.

We just had the same problem this evening. We'd be grateful is someone could tell us how we can have hyperlinks in the messages we send so that people can click on the link and have it work.
