On Drupal 7 / CiviCRM 5.25 I have 2 webforms with .
If I send the links through CiviMail to a profile that is a normal (test) member, update is already pre-populated and subscribe isn't. Of course, I'm trying in an other web browser where I'm anonymous.
I can't understand why there is this difference. It's the same profile, both webforms have checksums.
Any hint about a parameter I could check, knowing that subscribe used to work until recently and the datas were auto filled?
