——— EDIT:
I'm almost mad that this worked...
It's the "larger text" UI scaling causing the issue.
@miklos290 let me know if this fixed it for you??
See attached images for context, settings are under "display".
**** larger UI scaling breaks everything!
lol
Older folks need to see!! #accessibility

I now have my "search widgets" list on the left, in addition to the 8 big ones, after adjusting the UI scaling to "default"!!
(HomeKit buttons in StandBy, let's go!!!)

——— END OF EDIT.
I want to add that I have this EXACT SAME issue, and thank the original author for working to find a solution, I have not been able to find any fix or even mention for this issue, anywhere else online.
– Just updated my iPhone 17 pro to the latest iOS (2/16/2026) and StandBy is still broken...
– I can only see the 8 widgets as OP showed, not the side list of all available app widgets.
– I have "allow widgets" checked in my face ID/lockscreen settings.
It's funny i've never been interested in StandBy mode and when I finally do find it useful, it doesn't work, lol
There MUST be more than 2 of us out there having this issue??
Any ideas to troubleshoot this are very much appreciated!
I have a hunch it might be my "zoomed type" setting as that (way too)often causes UI problems, I'm going to try that and if it helps... I'll report back.
