Reminders on iPad doesn't sync with iPhone
Context: iPad A16 with iPadOS 26.0.1; iPhone 15 with iOS 26.01; Signed in to iCloud with the same Apple Account on both devices; Contacts, Calendars and Reminders are turned on in my iCloud settings; date and time settings are aligned.
Problem: Reminders aren't syncing; it appears that the lists on the iPhone and iPad are stored locally. All other services like iCloud Drive, Notes, Calendar, and Contacts are syncing correctly.
Tried all combination of sign-in/out, restart, reboot.
What else can I do?
iPad, iPadOS 26
