What version of the add-on boards do you have? The pin assignments changed a bit over time because, like GPIO 35, you can't use it as a CS pin. That was my mistake.
For the current pin assignments, take a look here: https://github.com/CircuitSetup/Expandable-6-Channel-ESP32-Energy-Meter#add-on-boards

I have v1.4 rev 1 boards, at least the ones I have access to. The last order I got from you is packed away in a case and I prefer not to mess with it.
Looking at the silkscreen for CS chip selects I see, 0, 27, 2? (hidden under header), 13, 14, and 15. Since the schematic is v1.3 rev 1 perhaps they have changed? I started with the chip selects in your example before digging into the schematic and trying those values.

Sorry I didn't see your last question sooner. Yes, the CS pins changed a bit between 1.3 and 1.4 rev1. See the link above. Let me know if you have any other questions!
