Many people had reposted similar problems with Mail on iPhone. However even with the latest iOS updates my problems still persist. Listing them here:
1) When viewing new mail and clicking the down arrow to get to the next new email, it shows each email twice. They are not listed twice in the inbox list, but if I'm in a new email and click down to get to the next new email it will show me the same email again. In other words, if I've opened up a new email and am clicking down through the rest of my new emails it will show me each one twice.
2) For some reason certain new emails do not appear right away in my inbox, however the do appear in the "Unread" folder. Once I view them in the unread folder they then appear in the inbox. I have not found a rhyme or reason why this is happening. It's usually around half of my new emails. The notification badge on mail will say 10 new emails. When I open Mail about 5 will be in the inbox (as well as the unread folder) and the other 5 will only be in the unread folder. This makes no sense since all new emails are coming to the inbox on my actual email account, evidenced by the fact that once I open them they then immediately appear in the inbox on my iphone.
3) It seems other problems I was having as well as many other people have been fixed, like needing to delete emails twice and sent messages appearing twice. But the above issues, which I always saw as related, persist. I've heard it is a Hotmail issue. None of these problems ever happened before iOS 13 and although updates fixed some things, other big issues remain.
