My prepopulated URL stopped working

I have been using autofill links for the past few months.  Today they seem to have stopped working.  I even found the sample link from your post and that did not autofill either.  Is there something that has changed?

Hello 😊 There hasn't been any reports today about the prepopulated URLs not working.

Can you give us the complete prepopulated URL that you're using so we can have a better look? Also, how are you using this feature? Are you passing data from one form to another or are you just using it as a standalone link that prepopulates a single form?
