Sync iOS Photos and Lightroom for iPad and Iphone

Hi

I allowed Lightroom to access iOS Photos "All Photos" on both devices.

initially i only had this setting on my iphone, all was good, then i did the same on my ipad, now if i get pictures send over whatsapp (as an expmple) the photos are directly going into iOS Photos app, and since i allowd Lightroom on the ipad to access all photos (i used this function just to manually add pictures) it automatically adds the new pictrues to Lightroom on Ipad and....syncs to the cloud and i have them in lightroom on all devices.... if i disable the function on ipad, but leave on iphone access to all photos this will not happen anymore.

i hope i described the case understandable. 

and hope for some tipps or help
