Shower backed up
My shower drains into the grey tank without issue until the grey tank fills to halfway, then the water backs up into the shower. The kitchen sink and front bath sink will continue to drain just fine, ...

How do you know the grey is not full?
When my grey is full, the shower (lowest) is the first to fill up. If I use sinks the water will flow just fine, but the shower tub will be filling higher while the sinks drain. Sounds like your grey tank IS full.
The grey dump sounds similar to mine. I always thought it was rushing at first cause it was full, then it slows, then the one way air vent kicks in (under the sink) and makes a big gas release sound ........anyway, your sounds just like mine
Maybe check those one way air valves under sinks?
I've started with the tank empty and filled the tank from the kitchen sink. When my gauge gets to half full, I have nothing coming up through the shower. When I continue to fill my gauge will go full, and then it will begin to fill the shower.
