Can’t speak for everyone but on my phone the a.lemmy.world website is unusable for replies. Half the reply box is covered by a control with a tempting x that closes the entire post and loses my reply. The submit button is hidden under the keyboard. When I finish typing I can hit the check mark above the keyboard which causes the website to zoom to 200% where upon I must find a neutral spot to double click somewhere and look for the post button, otherwise some nerd won’t be able to invalidate my experience.
