@cnalletamby @ClaraListensprechen@universeodon.com Yeah, there are some techniques to pick up. With some instances you can just click and follow someone.
If I click on a user, land on their Masto page, and there's no invitation to follow, I copy pasta their full Mastodon address, which is displayed. I then hit page-back to display my own search box, paste it, and hit search. This instantly pops up an icon I can click to follow them. I do it without even thinking now.
There might be a better way but the above works for me.
