This is also correct. If you clicked a button to create and save the deeplink when using the builder, you’ll get the wrong deeplink. You’ll need to click the button on the live app.
One tip for not needing an action to create a deep link is to go to the live website and copy the entire url. Then use a template column.
Example of a deep link in my app.
“https://thisdish.co/dl/a55b37/s/3ddb6b/r/51UqeVq2RbCURmqA7glnng”
So using the above link, the last part “ 51UqeVq2RbCURmqA7glnng” is the row ID of that particular item.
So using a template column, I would do:
“https://thisdish.co/dl/a55b37/s/3ddb6b/r/ROWID”
and dynamically replace ROWID with the Row ID column.
Then you can just share the temp column as your deep link.
