No issues here. I think the cause of your limp mode could be trans temp. If they are the same as automatic Evoras, it’s not uncommon for them to have issues with heat.
Same no issues here and I track in Texas, so the ambient temps were 95F+.
When I come back to the pits, I'll open up the hatch and let the car idle for about 5mins before I shut it down. I've never experienced a limp mode from heat with this practice. Never had cooling issues on track either.
