New error trying to load pictures on posts with an iPhone

Hi all,

I feel like with time, loading pictures on posts (I am mainly using an iPhone for posting), is becoming more cumbersome. Especially when copying a page to the clipboard and pasting it by long click-paste. The safe alternative has always been copying the picture to the camera roll and adding it by the add picture functionality of the post editor. Well, until now. I got an error message by trying to use this functionality, that I never got before:

It looks like there is some kind of image format incompatibility. Can you pls take a look into it?
