I tried tapping the link in the body of this post: https://lemmy.ml/post/7227071 and got a toast saying "Error opening link". Long pressing the text and copying the link works, so I guess there's some kind of parsing issue. The link was https://www.kcsoftwares.com/?sumo and the post has it formatted as https://www.kcsoftwares.com/?sumo
Boost version shows 1.0.1 (4) in the app info.
It appears that the formatting is what causes it. The plain link works but the formatted one doesn't. I haven't seen this kind of formatting yet but I think it wouldn't be too hard to add support for it.
It's the fault of the user who made that post. They used Markdown incorrectly. Plain text is supposed to go in the square brackets, and the url is supposed to go in the parentheses. [This](https://www.kcsoftwares.com/?sumo) becomes This.
They literally created a link that uses "url" as the url. Trying to click their link gives an error no matter which browser or app you use.
