I'm trying to export a collection of 259 songs to my Local File but when it's asking me where to save it, the options show as "Move 15 items" only. Need help please.
I'm not sure I can explain that - I'll have to see if I can find some way to reproduce it. Let's try a workaround instead:
1) Go to the Collections tab and long-press/right-click your collection to select it
2) Tap the three dots at the top right and tap "Create Setlists from Songs"
3) Enter the name of a temporary setlist and tap OK
4) Go to the Setlists tab, long press/right-click that setlist and tap Share->Export files. Select the destination and see if it correctly lists all 259 files.
As a side note, what export options have you selected and are any of the songs linked to blank pages?
