This issue confused me too, on my iPhone SE. The top action is copy and is partially cut off on the screen, and I didn't know save image was below it. At least it being cut off eventually led me to scroll down. Apple has destroyed UI intuitiveness by going too far in the minimalist direction. Sometimes we need some damn scrollbars or indicators. However, it appears this changes based on the app? If I long press an image to save it from the browser or from the Toot! (mastodon) app, I get the regular save image dialog that I've always gotten on iOS. If I long press an image to save it from Twitterific, I get the share sheet. Ugh. The share sheet annoys me too. I get the convenience of having "most common" contacts at the top to send things to, but most of the time this is in the way for me and I'd prefer it completely off and as expected with Apple's "features" they rarely provide options to turn them off. While I prefer iOS over Android, it's stuff like this that I realize is a big trade-off for me. Edit: Looks like I can at least re-order so "Save Image" is the top option... but it's still buried beneath the contacts and apps
