I have three user groups for my Bubble app.
I would like one user group (User) to return to their respective home page (page A) while the remaining user groups (Vendors A and Vendors B) to navigate to a separate home page (Page B).
Use conditional actions in the workflow to direct them to the various pages depending on their User Group.
You might alternatively use a link instead of a workflow action, in which case the simplest way is to use a dynamic link, and save that link in the database for each user.
