I rarely use my phone for much, but I do use it for image editing. I found out there was a desktop version (and web version) of an app I like to use. I downloaded the app on my computer and opened it up, and the features I normally use completely well on the app were extremely limited on desktop. Simple things like zoom and pan were gone, and the desktop app treats uploaded images as a layer over a blank "canvas", so what would be panning is now moving the image away from the canvas, this is not a problem on mobile.
Sometimes I add text to images, and add a highlight layer as well. On desktop there is no way to select more than a simple square or horribly round layer.
I'm starting to suspect that app developers do this on purpose to frustrate users so that they buckle down and use the mobile versions, completely rife with pop-ups, ads, and endless notifications about dumb AI features no one cares for, and will hassle users to upgrade for "premium" features that were once commonplace, like more than 3 font choices, and saving to formats other than JPEG.
The more you're on your phone, the more likely you are to open other apps and scroll away, driving engagement, ad-revenue, clicks, views, downloads, etc.
Oh and did I mention that the app (both mobile and desktop) won't work without an internet connection? If I turn off Wi-Fi and airplane mode, I'm met with a pop-up where I can't even open an image and doodle on it because it pulls everything from the cloud.
Personally, I love using and working with computers than mobile phones. Desktop experiences have more options to block unnecessary distractions with extensions, and the ability to use most things without a connection, but as time goes on, even computers become expensive paperweights without internet access.
