iPhone Not Backed Up warning
My iPhone apparently hasn't been backed up in over 3 weeks. I've been getting a message and it also says "Backups happen when this iPhone is connected to power, locked, and Wi.Fi".
My phone is plugged in every night and on WiFi. The only part I wonder about is the "locked" part. I use an app called "White Noise" that has a clock feature that stays on which seems to prevent the phone from locking. If this might be the issue is there anyway for the backup to happen without the phone being locked?
Thanks in advance.
iPhone 11 Pro, iOS 13
