I agree completely. One of the main reasons I used Evernote for so many years was the clipping functionality and specifically its support on IOS. When that disappeared with no explanation I thought it was just a temporary issue but it has now become clear the functionality is gone. I was already getting frustrated with the lack of responsiveness from Evernote and all the bugs but this one drove me to look for real solutions. OneNote is not a good replacement unfortunately and most of the 'alternatives' are not real alternatives in terms of being a true replacement.
I am curious if anybody has found something better but right now I am testing Notion (https://www.notion.so/) and it's turning out to be a very good replacement. Migrating was incredibly simple and absolutely EVERYTHING moved over fast and with nothing lost. That has let me run Evernote and Notion in parallel for a few weeks now and after some extensive tests with the Notion web clipper in IOS as well as my laptop I feel I am ready to call that a real solution. There are a few things I want to see improved on the web clipper features in Notion but I found them very responsive to feedback and when I had an issue they were able to help really fast.
All this to say... so far I think the only real 'Solution' is voting with my money and going elsewhere.
