So I'm doing No Nat November(to an extent) and you can check out what the plan is here. This is going to be the first of my posts on how things are.
The biggest loss here was Discord(though I still do have to use it, just reducing what I use it for) and slack. They are one to straight up have no AAAA record on their domain. This does suck because too much comms is still on discord. But I've been trying to slowly cut discord off more and more, and this has helped.
The winners for chat apps were: Signal, Telegram, Matrix(though this depends on your homeserver and if they support IPv6). Signal had no degradation at all. Telegram was a bit slow to load but once it was going, it was fine. Matrix is a crapshoot, but if your homeserver supports IPv6, then it's pure bliss.
On the Hive chat side of things, the Rockchat(https://openhive.chat/) worked fine. I was even able to log in using hive.blog with no issues, and the devs chat on mattermost worked as well. Extra props for the devs chat for not just relying on cloudflare for getting an AAAA record but actually setting one themself! And a fun one too, it has dead:babe in it. PeakD's sting chat doesn't work because it only have an A record and no AAAA. 
With the help of telegram bridges, I wasn't fully gone from some communities. I do think that this will help me reduce my usage of discord even more, especially since I'm realizing I can cut off some of it and not feel it.
LOL. None of my banks support IPv6, except for Mercury. This is one place that I had to reactivate it. I'll be reaching out to all of them and asking for support. I don't expect it to happen immediately, but I do know that some banks are working on it :)
I actually don't use very many streaming services. Youtube works fine(google actually has great IPv6 support). I think from the list that I have access to, Amazon Prime was the only one that didn't support IPv6. Due to their large scale and benefit they get from IPv6, a lot of streaming services already support it.
Hive related stuff is kinda fun. A lot of things are behind cloudflare so they have IPv6 support, but I bet it's not because they chose to, but just got forced into it(the only way to disable IPv6 on CF is to be on the enterprise plan, and that is $4k/mo minimum). Some services do have support which is nice.
PeakD is mostly usable. Some aspects are slow to load because they rely on services that are IPv4 only(hosted by other hivers), but once those things time out, it's good again. The biggest problem I see is that most services default to using api.hive.blog which only supports IPv4 and because of that, things don't load. 
The one issue with PeakD is uploading images. They upload to backblaze(which does support IPv6), but not sure what needs to be changed on their part to get it working. I've been using hive.blog to upload my images and come back here.
Hive.blog worked too. I really had no issues there, not even things being slow. If snaps were there(yes I know they are with the container post, but I mean in the nice way that it's displayed like on PeakD), I'd be more likely to use it.
Ecency was the one who struggled the most. While I could get onto the site, posts wouldn't load. I am assuming it's because they use api.hive.blog and don't have an auto node switch mechanism? But I didn't debug.
Other hive apps:
VSC: I can't even load their site.
Hive-Engine: Works, they default to a node that's dual stacked so honestly good job. But api.hive-engine.com isn't dual stacked so no access there.
WorldMapPin - No IPv6 record added. Someone from their team was promoting it and I wanted to use it because I like the idea, but without IPv6 support, I am unable to this month.
Things are honestly looking fairly good on IPv6 support. I'm seeing more and more applications support it and the internet is not completely unusable on IPv6 only. I'm hoping by the end of the month we see some more services(especially hive related ones) support it!
