Issues with the FCA1616 and Mac OS Big Sur M1 chip?

New

I have the FCA1616 and used it these past two and half years using a PC Windows 10. It had issues of intermitten noise, but that slowly went away over time and became very reliable. I switched to the Mac Mini M1 this year and it cuts out all the time. I tried the UMC404HD and that seemed to work, but I'm using that for live shows. Should I upgrade to the UMC1816?
