Don’t stress yourself y’all. Just check the junk folder of me@icloud.com. It may take a minute to download all the junk email. There, you will see all the missed emails. Kindly move all the emails you desire to the inbox of me@icloud.com
try sending an email to me@icloud.com from another email address. the new email should be found in the inbox of me@icloud.com and no longer in the junk folder.
this worked for me and I hope it works for you too
