I have a quick question, apologies if it has already been answered.
Based on the usual roster of podcasts, I heard many rumblings early in the beta process that upgrading one device (say an iPad) to iOS 13 but not others (say an iPhone) would create specific iCloud and app based issues. For instance, Reminders would no longer sync between devices. Generally speaking, there was a risk of breaking the integrity of iCloud and syncing between devices.
If I upgrade today to iOS 13 on one device but not others, will it break iCloud on legacy devices? Have there been any reports that iCloud Photo Library is problematic if certain devices remain on iOS 12?
Thank you for any guidance/help.
