When doing an outdoor activity, I would allow my precise location on a run.
It is well-known now that anonymizing location data still does not preserve privacy: https://iapp.org/news/a/getting-lost-in-the-crowd-the-limits-of-privacy-in-location-data-2/
Comments are pushed out by the community's server, they're not pulled in by yours. So if you're missing comments from communities hosted on lemmy.ml for example, it may be that lemmy.ml is overloaded and not sending out comments to the fediverse properly.
The other common issue with missing comments and posts is misconfigured language settings in your profile. You need to make sure at least Undefined and English are both selected, lots of people only have English selected which will make a lot of posts hidden.
I prefer the browser to apps personally, this is actually one of the main reasons I like Lemmy over Reddit and it's unusable mobile view. You'll find plenty of mobile app users here too and it sounds like it works fine, I'll just caution that some (all?) of them sound like they're feature-incomplete, so if you ever think something is missing from Lemmy, double-check on the website first, because it might just not be added to the app yet.
The biggest problem to me is what I just saw you post in another reply, that these models built upon our knowledge exist almost solely within proprietary ecosystems.
and maybe even our Mastodon or Lemmy posts!
The Washington Post published a great piece which allows you to search which websites were included in the "C4" dataset published in 2019. I searched for my personal blog jonaharagon.com and sure enough it was included, and the C4 dataset is practically minuscule compared to what is being compiled for larger models like ChatGPT. If my tiny website was included, Mastodon and Lemmy posts (which are actually very visible and SEO optimized tbh) are 100% being scraped as well, there's no maybe about it.
I would describe Apollo as an accessibility app in the sense that the regular Reddit app is unusable.
Click the copy icon to the right of the community name on the search tool, then go to https://lemmy.one/search and paste in the URL it copied, and the community should show up. If it doesn't immediately show up: wait 30 seconds, refresh the search page, and try again, and then it will work.
"The content" on all Lemmy instances is the same. There is no account migration, but you can just sign up on lemmy.ml. If you already had an account there and you want it back... I don't know if it's possible for an admin there to restore it, you might have to get in touch with them.
Just my password manager and uBlock Origin :)
I mentioned Lemmy on Mastodon and some people noted some controversy surrounding the "main" instances. I don't know exactly what concerned people, but I definitely think that more bigger, possibly saner instances like beehaw.org and—hopefully—now lemmy.one can make a better first impression on users.
Also, federation with non-Lemmy platforms seems to be much better than it was last time I looked at this place 6-12 months or so ago.
I think there's a bug somewhere :)

Mods available to be added?
Not sure what you're asking here? About creating communities (subreddit equivalent) and adding mods for them, see my comment here: https://lemmy.one/comment/536
You can collapse comments, it's just not really intuitive, click this button:
No downvoting on lemmy.one:
Downvotes are disabled on this instance, because it is a very small community. If you see something against the rules, report it. If you see something you don’t like, go find something you do like and upvote that instead :)
I may consider changing this in the future.
If you have more questions about this instance, lemmy.one, generally, you can also ask at !meta.
Can you self-host, or are you looking for another online service? Facebook Groups is basically a forum when it comes down to it, and any forum software can do what you're asking. I really like Discourse. You can self-host it for free (well, whatever your server costs), they'll host it for free if you're an open-source project, or if you're a legal non-profit you can get 50% off their hosting for $25-50/month.
