It’s a technical thing that someone can probably explain in more detail, but once other instances start pointing toward your posts on lemmy.ml or whatever your domain is, then changing your domain later on will break that at minimum (there are probably worse consequences, but like I said I don’t know everything under the hood)
There’s not really a way around getting the app, it’s all closed-loop proprietary stuff. I believe that you can browse on the website if you’d prefer, but you’ll still need an account for it to be worthwhile, and most of the content is designed for mobile screens.
Just like most corporate social media you will need to make some compromises on your privacy and data sharing to use it, but it’s not necessarily worse than any other apps of this type.
Edit: Ignore this for now, I thought I’d gotten past the original issue.
Next question is how to get content from the comm to show up in my Mastodon feed after I follow.
I understand that being the first person on my instance to follow a comm will mean that my instance won’t preview any content, however I’m not seeing anything pop up yet now that I’m following.
