I just migrated from CM12.1 to LineageOS 15.1. Wonderful ROM!

I used to backup with LP my app on external SD card.

But since, I have a problem with the directory path on my external SD card.

Before, the path was of type: / storage / sdcard1 /

Now the path is of the type:

/ Storage / 6200-1E02 /

So I have a problem: LP can no longer access the external SD card. LP didn't recognise this path.

Do you have an idea for dealing with this problem that had prevented me from migrating to higher versions of Android?

thank you so much
