I cannot sign PSBT's with my coldcard. I use the latest version of Sparrow wallet. I manage to save a PSBT file on my sd-card, but when I put the sd-card in my CC and press "ready to sign" it doesn't find the PSBT but says "Coldcard is ready to sign spending transactions".

I have already updated Coldcard firmware to the latest version but it won't help, I have also updated my Sparrow wallet. The SD card has been delivered with my coldcard (so it is from coinkite) and it has been formatted in FAT 32.
