Why Can't I Post Things On My Phone?

Hello everyone, how's it going!? So then, I've been on here for a week now, and when I log in here with my laptop, I'm able to post topics and comments just fine, but whenever I log into my phone, I can't do so. Does anyone know the reason why? The bot verification thing doesn't appear, so I should be able to post normally on mobile, but for some reason, whenever I try to post, nothing happens. Would appreciate help in clarifying this! Thank you!
