Confused about 2 app installations / data sharing and backup

Ok so i had Locus Map 4 installed, from which i have downloaded LoMap of my region (3 free downloads) , i have changed the root directory to SD Card because i figured it will be easier to keep it backed up here in case i have to factory reset or something which wipes internal storage, so i think it was downloaded to /android/data/menion.android.locus.rpo on SD Card.

Later on i decided to buy Locus Map Pro, i installed it when Locus Map 4 was still installed also and ran it, afterwards i uninstalled Locus Map 4 and i cannot access the LoMap i downloaded earlier.

Currently default root directory is on Internal Memory Private Storage, i tried changing it to SD Card Private Storage but the maps are still not available.

Why this has to be so complicated and confusing? Am i doing something wrong? Are the LoMaps i downloaded earlier are lost and i lost the "1 free" download?

Also even if i decide to download LoMaps again how am i supposed to backup them since i can only install them in the "Private Storage" either on internal memory or sd card which i cannot access (i'm not rooted), the "Internal Memory" is greyed out and says this directory is no longer supported.

I'm on Android 12.
