My Reminders do not sync

I have searched most, if not all, threads related to Reminders and have not found my answer.

Here's the problem: My reminders do not sync. My iPhone is at iOS 14.4. My MacBook Air is at Version 11.2.2. I only use Reminders on my iPhone since they stopped syncing with my MacBook with the introduction of iOS 13 !!!

My solution to the problem was to not use iCloud for Reminders and only keep them on my iPhone. It works. But what a hassle ! I want to see them on both my phone and my MacBook. Is that too much to ask, Apple ?

Since that huge mistake by Apple back in 2019, I have tried time and time again to get my Reminders to sync. What I do is first print all my reminders (painful as I have to take screenshots and I have a lot of reminders). Then I go turn on iCloud for Reminders. Once I do this, all my Reminders on my iPhone are gone. So, now that I have iCloud re-enabled for Reminders, I enter them all again from my printed screen shots. And? Nothing. Sync still does not work. So I have to turn iCloud OFF for Reminders and only use them on my iPhone.

Do others continue to have this syncing problem ? Have you ever found a real solution ? Does Apple ignore you like they do me ? Thanks for any information I can get.
