Issues with sync when moving Lr from old iPad to new iPad [was: An obvious issue!]

There are issues with IOS Lr app for i-pad! There needs to be an on/off toggle for sync with off in default mode, sync should start with high resolution as default status instead of smart preview, and you should'nt be able to erase images across all devices without at least a prompt asking you for permission. Through a 

series of unfortunate events I lost years of work and 1500+ images and im devastated! I deccided to move my images from my old i-pad to a new i-pad, the sync started instantly without a prompt as soon as I opened both apps, unfortunately smart preview is the default setting so I decided to erase the images downloaded on

the new i-pad so far and start the process over. When I did the app told my original i-pad to do the same 

and now the images are gone forever. You could say the cloud will save them, and yes, the smart preview low res version. I shoot macrophotography, the quality and sharpness matter. Those images mattered! This app is for people striving for the best image possible, why on earth would the syncing be set to default as a low res version. I just dont get it!
