I absolutely did authorize it. A separate tab to the Enphase opened, I authenticated, and was told that it was successful. The page was slightly different for v2 and v4.
There was no feedback whatsoever in the PVoutput tab reflecting that anything changed, though.
I saved the PVoutput system settings afterwards. It made no difference.
Are there specific browsers that need to be used ? I’m using Firefox 102. My privacy settings are set to strict. I also have Adblock plus and Ublock origin.
