I searched a lot for this question; found this question (How do I transfer app data from my old iPad to my new iPad?) but it's from nearly a decade ago, so it may not be relevant.
I will be buying a new iPad (2020) and trading in my old one (from 2017). There is one app (Multicraft, an offline version of Minecraft) which I have spent a lot of time using, and considering the amount of time I have spent creating things with this app, I'd like to keep all the data.
My question is: How do I re-download the offloaded app (with data) from my old iPad to new iPad? Has anyone done this recently and confirmed that their method works with various types of apps?
