Hey dev.to team, I can't really comment on my phone. What are the best steps to take?

Just left out formalities so you see my point straight, I hope you are having a great weekend.

I'm on iOS latest (beta) - ~11.3 and the Safari coming with that version.
Commenting works fine on my computer, I tried logging in and out on my phone but no luck. What do I do wrong? Is it only broken for me?

Thanks for the help in advance, I hope this is the best way to report bugs, if not let me know how.
