I found this support forum post but the solution provided doesn’t work.

Yes, my default search engine is Ecosia.
I haven’t changed it manually though, I installed their extension and it changed the default; if this matters in any way.

Thanks. Because of this post I was able to figure out how to change the search engine on my phone
