I was just suggesting that if you think it was so easy to fix by now, how come you haven't fixed it? It DOES seem like you're very mad at this situation. As I have mentioned, there are other mail reader apps available on the App Store. I have tested a few of them with my iCloud.com email address. I keep going back to the Apple Mail App because I like the UI. That is all. If I found another app that I liked navigating through, I would stick to it. I haven't.
If you're in contact with the lead person on the development team, then he surely has explained to you the intricacies of writing code and how complicated it can be to find the part in the source that is causing an issue. Also, it may be more than one spot in the source and to comb through thousands of lines to find it takes time. If it was so easy for him and his team to fix, I am sure they would have released such a fix by now. Personally, I have been talking to a support rep who has been in contact with developers and I have been helping to provide them information such as logs and my description of what I am experiencing and truly trying to help them troubleshoot. All for the greater good. I am happy to do so as they may find the answers in the information I may be able to provide and then be able to correct it and release the patch in an update. I come here to report my findings to inspire others to try some of the steps I have made which can encourage them to contact support and tell them about these reproducible occurrences. Do I wish this was fixed by now? Yes but, I understand that we have to help provide evidence of the issue to get to the root cause.
It is just email. It's not that serious. If you're depending on your email as source of communication for business or other important matters, which I understand could be the case and the cause for your obvious frustration, then I politely suggest to you, again, to visit the App Store and pick up one of the multitude of free apps available that has the potential to serve you better than the Apple Mail app until such time as Apple and its developers have been able to squash the bugs.
So let's be productive and try to function as a 'community' and try to help each other rather than insult each other.
