I updated to the new app a few days ago and since have noticed more often than not the sync icon in the toolbar and when i drill into the sync menu it is sitting there syncing instant upload photos, also my data usage has shot up by around a gig this month.
I suspect this is the high res photo support and that maybe it is re-uploading the pics off my phone, if it is I suspect there will be a few data cap overages amongst the ranks if peeps aren't careful
Anyone else had any issue?
