This is a major reason I am thinking of switching from opera on mobile.
Reddit Links don't open in my Reddit app. I can only choose to open them in the default app when I click them even though Chrome readily opens them for me in Reddit is Fun.
YouTube links don't open in YouTube. This is pretty frustrating because I use YouTube Vanced which allows for background play, etc.
Honestly the only reason I use Opera anymore is because it's the only browser that has decent text wrapping/text reflow. This used to be default in Android webview until Google forced it away to try to make more websites roll out decent mobile views. However what Google didn't realize is that people with visual problems like myself have a hard time seeing pages and when you zoom in it sucks having to scroll left and right.
However a recent update to Chrome added the zoom option right in the menu so if you need to scale up the text it's a lot easier these days and you don't need to dig in the menu every time.
Not to mention Opera on desktop and Mobile keep adding ton of useless features that bogged down the browsing experience. I don't want to built in VPN when I subscribe to my own.
I also sometimes find web pages that don't support opera. Sometimes they will outright not let me view the page if I don't switch to Chrome. Other times certain functions just don't work. For example I had to upload medical records from a CD in my CD drive to my doctor's office using a web app. Even though I kept browsing for my d drive and selecting the CD it wasn't detecting the images. I thought the website was fucked up. Then I decided to try it in Chrome and it worked first try.
Is text wrapping worth all these shortcomings when Google has the zoom feature anyway that mitigates most of the pain? I wish the zooming would work on the fly but what they have is pretty decent.
