Some general issues

A few things are irritating me at the moment - help appreciated.

1 - iphone/ipad photos not syncing to PC, having to download them "longhand".

2 - since recent update not getting on with music app at all - all playlists wiped and unable to reinstall.

3 - not all music syncing; dotted circle of annoyance next to a lot of tracks.

4 - music app no longer remembers what was being played when it was shut down.

Any tips?
