Had this problem almost a year. Images from download/save button to IOS both Iphone & Ipad are double height & width. (4x size)
ie 585 images are 7680 x 4324 (33MP) instead of 3840 x 2160
Images from 178 are 6192 X 4160 instead of 3096 x 2080
Saved fits files on the AA+ are correct size. The change occurred somewhere betwwen 20 Feb & 20 Apr, I'm guessing due to a dodgy update.
The not so obvious problem hits when doing live stacking with short exposures, Continuously sending 33MP doesn't work well.
Android is unaffected, downloads are correct size.
Please get this sorted. The asiair is becoming "Not fit for the purpose"
