I used to save my attachments on my external SD with my HTC Sensation XE under Android 4.03.
I now changed to a Sony Xperia Z5 Premium under Android 7.0. A 128GB SD is intalled, in General Settings of K-9 the path to a folder on the SD is set, in Account Settings of K-9 external memory is set and in Android 7.0 App settings writing on external memory is granted for K-9. Despite all this whenever I try to save an attachment I get the error message "Saving on SD memory failed". I am using the most current version of K-9. What can I do?
