I don't understand how Samsung came to the decision to not allow gallery syncing with SD card. Before 'merging' Samsung Gallery sync with OneDrive I was able to sync and backup gallery contents (both internal and external memory) to Onedrive. Now I can't without resorting to some convoluted workaround to try and make it work again. 😡
Currently, I have Gallery sync disabled and Onedrive media sync enabled in account settings. Only issue is Onedrive media sync will automatically be disabled due to the Gallery sync (even when it's disabled). I need to go back into account settings and enable it again.
I even went a step further now by actually removing Samsung permissions from Onedrive in hopes it will not automatically disable the media sync. I'm crossing my fingers and hope this does the trick and resolves it.
