I found a similar post from late 2022 that was solved, but I feel that the issue has resurfaced. I created an interactive legend app around October 2024 and everything worked. I recently found that the widgets are gone from the app.
1) I have my layers unhidden in my map
2) While configuring, I toggled on these widgets: search bar, bookmark, export, and basemap toggle
3) I made sure to publish
Again, the widgets originally showed on the app and worked correctly, but none of the widgets show up now. I even tried to make a 2nd version of my app and still no widgets. Any information would be appreciated. Thank you
