Gregory's ServerWith this description I'm not sure we mean the same thing with "the mobile version". In my phone I use my web browser to visit the website. That is often what I mean with the mobile version. In this mobile view I can edit my profile.
My understanding is that you're referring to an app installed on your phone? When it comes to Mastodon there are many apps available, albeit one official app.
But yes, you can't always edit your profile in mobile apps. I myself avoid all Mastodon apps. 😁
