Data for just one app not backed up?

Hi! I am having issues with my new phone, I wetn from a Moto G6 Plus to a Samsung Note 10 Lite this friday and went through the proccess of cloning my apps from the old phone to the new phone. I used Samsung's Smart Switch app and most of my info went through flawlessly....except for the data in this one app I use to register all my finances.Basically it has the info of every purchase and deposit I've made/recieve since the last year. I thought the info would clone over with smart switch or get pulled from the app store if it was somehoe backed up in there. I tired unistalling the version that got cloned and re-install it from the Play store with no luck, the app just sets as if it was new.I still have the old phone with the info, is there a way I could get the info over the new phone? I am willing to reset the new phone if neccesary and transfer the info in any other way.Thanks for taking the time of reading my issue and sorry if my english looks weird.This is the app, I submitted a question but I've had no answer so far. https://ift.tt/32xnUcw
