Trouble connecting iCloud custom domain email with Wix

HELP! I am SOOOO FRUSTRATED! I have been trying for weeks to take advantage of the free iCloud custom domain email. I just can't get it to work with my Wix website. I have read the other threads on the topic and tried several suggestions. It is annoying because very time I try something I have to wait 72 hours to see if it worked. My domain is managed by GoDaddy and connected by DNS. Name servers are at Wix. I have attached screen shots below (with my personal info covered)

So I keep getting the iCloud error message "Check My DKIM record" or "SPF record", which I have and it doesn't seem to change. Here's what I have tried regarding editing my DNS & MX records: I entered the line that iCloud provided without the quotes and ending punctuation as it would not accept it with. It wouldn't accept the @ symbol so left that blank. I have tried entering the TEXT (SPF) and DKIM (CNAME) in the TXT box Wix provides rather than the ones labeled CNAME & SPF as that was suggestion. I tried deleting all of the old "extra" CNAME records that Wix told me were not required for site function, leaving just one Wix line there. I tried deleting the domain from iCloud and starting over. And now I just tried removing the CNAME & DKIM/SPF from the Wix TXT section and putting them back in the indicated sections (CNAME & SPF). (Currently waiting the 72 hours but not optimistic.)

One thing that I do notice but am wondering if it could be an issue is that iCloud says to enter the 2 MX records (mx01.mail.icloud.com. / Priority10) & ( mx02.mail.icloud.com / Priority10) but Wix keeps populating it with mx02 at priority 10 and mx01 at priority 20. There is no way for me to change both to Priority 10 and for some reason it insists on moving the mx02 to the top line. Any chance that could be an issue?

Apple support wasn't very helpful and just tried to get me to update my operating system which I can't due to limited storage, but I can't see how that should have any bearing on this as I can update the records from my phone or another computer. It's all online not on my hard drive. Am I wrong? And Wix isn't very helpful either.

Any suggestions? So frustrated. Do I have to just suck it up and pay for a custom domain email? Has anyone got iCloud to work with Wix? Thanks!
