Simionic G1000 iPad app crashing on startup

I bought the PFD app on my old iPad Air 2, and I successfully connected it to the sim, but each time I try to open the sim in the Cessna 172, it keeps crashing on startup. And also, it doesn’t work when I try other planes. I have tried multiple times and different configurations in the G1000 bridge, and it still doesn’t work. I have already asked them on the contact us page, just thought I would also ask here, because its also a popular product.
