Photos&Video flow management: Lightroom Mobile and iPhone native Photo App

[Regis5C96]

Is it possible, or do you have a tip, to delete rejected photo flagged throught Lightroom Mobile on both Lightroom Libraries and iPhone native photo App ?

I'm taking photos and video throught iPhone 12 Pro Max native Photo App and them import them through Lightroom Mobile.

This will allow me not to do the selection two time to free up space on my iphone.

Or do you have another optimal way to proceed ?

I do not use iCloud Apple services.

Thanks for your advices.

As they are separate and not linked the only process I know of is a manual one.

Agreed it is a pain, maybe create a feature  request (if deleting from the Canera Roll via a third party app is even possible) in the Ideas section of this forum, if there isn't an existing one that you can vote for.

A third party app can delete from the camera roll, but once the photo is copied to Lightroom it is a separate copy, so the connection with the camera roll copy is lost. Maybe it would be possible with a Shortcut script, but I never tried that.
