This works just fine for me. From the error, it appears like you have not given NewPipe storage permission. Could you check that you actually gave it the permission?

[johanw666]

I just checked, I did give it storage permission.

[triallax]

Ah, wait, I missed the fact that you were using removable storage, which is probably the cause. For now, can you check if you can export the database to your phone's internal storage and move it to the external storage?

[johanw666]

Yes, exporting to internal SD works fine.

[johanw666]

Unfortunately switching on SAF gives the same error.

Could you check if this apk from #5415 solves the issue?

[johanw666]

Yes, this apk can export the database and settings to removable storage on my Android 10 device. Thanks.

[johanw666]

This still does not work in 0.20.9, when will this PR, #5415 , merged?

[Thewisem]

Same for android 7
