I lost photos AND a previously purchased preset!

Hi there,

Thanks for reaching out. We're here to help.

Which version of Lightroom Mobile are you using? Did you change the location of the images? 

Are you subscribed or on a free trial of the application? Was there a phone reset or installation of the application?

Please ensure you are signed in to the app using the correct email ID.
Can you log in to the cloud,  lightroom.adobe.com, and check whether your assets are synced? 

Please check this post on our community which discusses how we can try to get our lost assets back:

Let us know how it goes.

Thanks.
