DNS over TLS/IPv6 issues- Apps don't load data over Wifi

New Fairphone 6+ owner and I absolutely love it. However, I’m running into the same issue as this thread mentions. I have about 4 to 5 applications that don’t work at all when I have my WiFi switched on. It’s definitely the same IPv6 problem.
I’ll be following this thread to find out and hope that there will be a solution soon. I have one application that it’s quite important (personal details, government issued, etc) for me to use and it actually gives me a connection error when the WiFi is switched on.
Thanks all in this thread for the temporary solutions, they are usable at least.
