This problem plagued me with my 16" macbook pro when Big Sur came out. It's pretty clear that Apple only cares about Apple-chipped macs anymore. Intel got the big boot when their M1 chip came out, and apple just doesn't care to support or optimize for it anymore. I started using windows about a month into Big Sur, and it's just so incredibly snappy and fast in comparison. I updated to the latest version of Big Sur the other day, and the issue persists. I have a $3000 intel mac that I can no longer effectively use because of this. This is greatly insulting as someone who has been a mac apologist for years. I never thought I'd say this, but after getting over to the Windows side and seeing how functional that world is compared to this mess, I'm done with buying new macs. I've also got my next phone picked out, and it won't be an Apple one.

You should not, if the organization that owns/submits the app is the church. My app does this. The pastor is the "account holder" for the app, and we had no trouble submitting, etc. Incidently, you may be able to get the $100 developer fee waived if you go through Apple's non-profit process. It's not a guarantee, but it's worth a try.
