Have been using this process for 3+ years. Today does not work. Create screenshots using screen capture (cmd-shift-4) moving cursor over iOS Simulator in XCode Insert captured image into Pages adding background color and text using sRGB color space for all items Export as jpeg and size in Preview to correct dimensions (e.g. 1242 x 2208 for 5.5' Display) Accepts first upload when second screenshot uploaded first is erased/coved with red box with error message -- One or more screenshots aren't in the RGB color space Has been happening for 4+ hours. Tried generating and savings as PNG same error occurs Have 6+ other successful apps no clue why this is happening. Appreciate any help.
