Your problem
My problem is: Dynamic content does not work in the Safari browser.
I set up 2 slots: 1st slot is with form and should be shown when the client doesn’t have a cookie and another if it has (already submitted the form). What happens: form appeared but after submitting the form pop-ups again. In Chrome, Edge, Firefox it works correctly (changing the form to the content of another slot)
These errors are showing in the log: none
Steps I have tried to fix the problem: disabled privacy -> cross-site tracking, and disabled blocking cookies.
