Old user back here, but needs to get warmed-up!

Hi all!

I'm an old user of this service, right from 2020, but left at 2022 because of rebranding and removal of free plan.... Now, the free plan is back, so I am!

Can y'all tell me how to customize mobile menu for my site with the "BetterGram" template?

Also, the feed width for mobile is too narrow so it looks weird... how can I change this?
