At home, I use an Android 16 Pixel phone, and a Chromebook, and I would suspect (but cannot prove) that 100% of my LAN outages can be blamed on the dual-stacking nature of IPv6 plus IPv4.

Chris Siebenmann has written extensively on IPv6: https://utcc.utoronto.ca/~cks/space/?search=ipv6

Google has some weird way of asserting connectivity, and I suspect that when connectivity on one protocol is lost, it is impossible to maintain or establish connectivity through the other one (IPv6) even if it is available upstream.

I am rather infuriated with the status quo at this point, because it is impossible to disable IPv6 on my devices and it is also impossible for my ISP to disable IPv6 on my LAN or on the CPE router which they own and control.

Due to chronic WiFi issues I was eventually forced to place my ISP router into Bridge mode permanently, and I use a 3rd party Netgear which I own, and does not have the same WiFi issues, and where IPv6 is optional (and often fails, because its implementation is buggy and glitchy for no reason.)

I am rather infuriated that it's impossible to disable IPv4 on my devices, so does that make us even?

		Yes I believe so! I recently purchased a brand-new LaserJet printer, and since it needs nothing to do with the Internet or a WAN outside my home, I thought it'd be great to simply disable IPv4 and stop doing the DHCP dance. Well it immediately fell off the net completely. I couldn't figure out how to expose its IPv6 address or contact its management interface. Hypothetically, Bonjour and mDNS should make this a no-brainer. Hypothetically, disabling IPv4 shouldn't even prevent it from connecting to the Internet. But I was ultimately forced to factory-reset it. IPv6-only LAN makes a lot of sense for most people, and perhaps reduces attack surface a little. If you have the means, I highly recommend setting it up!
