Yep. This is a new system, new account, and me new to solar!
Also, your suggestion worked! I logged out of both Enlighten and PVoutput, and upon logging back in to both, the authorisation worked like a charm.
Next step is to get that donation done, configure the updater to ‘both’, and then start reading the manual while the data starts streaming in - hopefully more impressive data than today’s wet, cold, and grey day produced.
Thanks @bankstownbloke !
