So I opened my iPhone app and when it synced to the cloud it popped up a message saying there was a problem with my local data cache and that I copied it to some /var/... directory that was too long to see the whole thing in the message box. And then it synced with the cloud and the 8 newest dive logs disappeared.

I recently had a similar problem, probably for different reasons(since I 
am not an Apple user). This is the weakness of not allowing a straight 
divelog download from the cloud, so that you know exactly what to expect 
on the local device. Sync does not do a straight download, but a 
function of what you last edited locally and what is on the cloud and in 
my experience what you get is often not what you expected since you have 
more than one local dive log (one on each device) and a sync on each of 
them often does not result in what you expect. My advice would be to do 
your dive log download from dive computer as well as editing on one 
device only, either phone or ipad, and to use the other device for 
viewing only.

Kind regards,
