I'm having an issue, it has started downloading images on a cropped format like 750x750 or 540x540 even the source image is and appears bigger (Version 1.37)
This happens to Stories, I don't seem to have this issue with feed images, also I haven't been able to download any video in a long time, but I could before.
It's sad to see Opera mods delay app updates, best of luck, this app is easy to use and extremely convenient for sharing those memes all over (since insta removed some sharing options from a lot of people)
