Email trevbeatsmultimedia@gmail.com and say which device you are on.
You told the app iCloud Photos is on and chose to keep deletes locked, or you have not answered yet. Tap the yellow banner on the home screen to change it. With iCloud Photos on, deleting a photo here also deletes it from iCloud and your other devices.
Deleted photos and videos wait in Photos, Recently Deleted for 30 days, and deleted files wait in the Files app under Recently Deleted. Empty those and the space returns right away.
DELETEONATOR only opens folders stored on the device: On My iPhone or On My iPad and the app folders inside it. iCloud Drive and other cloud drives are refused on purpose.
You gave it limited access. Open Settings, DELETEONATOR, Photos and choose Full Access.
Plug it straight into the Mac with a data cable (not through a hub), unlock it, and tap Trust on the device. Then press REFRESH. A cable that only charges will not work.
Sizes come over the cable and can take up to a minute on a full device. Keep the device unlocked while it reads.
Unlock the device and try again. Some built-in Apple apps cannot be removed at all.
Go to the DELETEONATOR page, tap “I already bought it” and enter your checkout email.
iPhone and iPad app: iOS or iPadOS 17 or later. Mac app: macOS 14 or later, Apple silicon or Intel.
