Thanks Wim, what you have outlined makes a lot of sense. V12 seems quite a bit more resource-hungry to me. I would have thought though that the tech. dept would run regular tests on a “consumer grade” set-up, so they know how it is working for us mortals in the outside world. Maybe they don’t do this.
I can confirm it is both Demo and Live accounts that are affected.
Hopefully phoentzs’ request to Nicolas will get us an update.
