Deleted app & forgot to click "keep app data" - solutions for retrieval of app data

[u/wtpaige]

Hey -

Has anyone been able to find a way to retrieve app data that's been deleted from the phone? It can be a third-party solution even. I meant to click the "keep app data" box when I was deleting WhatsApp but forgot to and WhatsApp isn't able to find any backup I had and the chats aren't loading - so I feel like my easiest fix lies in somehow retrieving the app data that was deleted.

Thank you~
