An add-in named 'Forms Builder' is deployed to app catalog 'Apps for SharePoint'. After modifications to the add-in code, I clicked on 'Deploy' via visual studio and cancelled it realizing the site URL was set to PROD Site URL. But , this step made the app disappear from the site contents, though, it was available in App catalog. So, I downloaded the same version and uploaded it again but it still wouldn't be seen in the site contents. Therefore, Added the app explicitly via 'Add an App' but the lists that were associated with this app were deleted and now they are empty.
I am helpless and can't figure out why the app was deleted from the site contents. Is there a way we could get back the previous app? or any solution to come out of this situation? Can someone please help me with this situation. Any help will be greatly appreciated.
Thank you in advance
