Obsidian has a problem with text expansion. This problem happens with Typinator and Alfred snipped expansion. Does not happen in any other app on MacOS.

The same problem happens when text expand in the note title (file name).
This problem has been reported earlier but nothing was done about it.
moved to help.
Sometimes configuring the way these text expander work, helps. From emulating a keyboard to copy paste or vice versa.
This seems like an Obsidian only problem. Don’t see this problem anywhere else. Also can be replicated with two different Text Expansion apps.
