This has tripped me up a few times, and I do not see it mentioned above as a concern/problem.
I am not in the habit of checking Upcoming changes by clicking the menu option on the left:
https://xyz.discourse.group/admin/config/upcoming-changes
That page includes a Preview link for each change.
Normally, as part of my daily routine, I check the Discourse inbox and sometimes find a notification about upcoming changes, for example:
https://xyz.discourse.group/admin/config/upcoming-changes?changeNamesFilter=enable_ai_bot_starred_conversations
Notice the change in the URL, and also that the Preview link is missing.
That missing Preview link is what has been tripping me up for a few days. I knew the link existed, but thought it had disappeared.
Hopefully this provides enough detail to understand the concern and possibly fix it.
