LocusPro sees only SD as Read-Only but it is already read & write
LOCUS READ ONLY 128GB SD: I use a Samsung Galaxy S5, Android 6 with a 32GB external SD card (FAT32) for map store for Locus Pro; it has been working well in NZ, Denmark, etc.
HOWEVER, I recently inserted a new 128GB SD card (exFAT) and copied several files and apps to the 128GB external SD card. I have run checks on the 128GB card using an adapter in the PC and all is working. Apps such as MS Word and Excel and all other apps transferred to the 128GB SD are working well, so the 128GB SD card is recognised and is Read & Write. BUT Locus Pro keeps telling me that the external card is “read only” and will not access the Locus Map Directory. In the Locus Pro App (that I have kept in the Mobile internal memory) I successfully changed Locus/Settings/Miscellaneous/Default Directories and have Set “maps/” directory to storeage/0000-0000/Locus because that is where I have copied the Locus maps; the directory is shown as blue (not red). I have restarted mobile phone several times to no affect. I have also set Settings/Maps/Maps/ Maps General-Offline/Personal & LoMAPS/ to Auto-load maps of any type. PLEASE WHAT DO I DO NEXT??
