No worries, there's a few threads here on the forum of a lot of discussion around wireless issues on 21.02 with a lot more detail and comments from developers and much more experienced individuals than myself, but I've just tried to summarise the situation.
I'm potentially going to try 21.02.2 when it gets released, given 19.07 branch goes EOL in March 2022. I've been deliberately holding off and I'm not exactly looking forward to it, given the wireless related issues and the whole DSA migration aspect.
