How can I become a better content creator for mobile? (Patreon)

I'm a very PC-minded person. A bit of a tech boomer honestly, not gonna lie. I work from my PC, I use my phone to either call or text people and not much else, and I use social media on PC rather than my phone also.

I'm probably god-awful at delivering content easily and accessibly for mobile users and I think this has been an achilles heel for me for years. But I also honestly don't know for sure because I just don't think about it and I actually don't even test it. So the question is: how can I be better? Also please rate how bad (or good?) I am at it right now.

Basically I'm looking for input from very mobile-minded people. I'm open to any and all suggestions for improvement :) If this is a big avenue for improvement it's time to do it.
