And you know what they’re aware of and not aware of how? Also, that’s a lot of code to go through to find what may be something as small as an incorrect or missing character.
There are other mail readers available on the App Store. I have successfully used one. I prefer the Mail app on the phone and I can deal with the minor inconvenience of my messages not being synced across my devices until they fix it.
I would participate in the beta program if I had another device to use but since I only have one I will not do so. As I stated, I have been closely working with a rep and giving them all kinds of information and helping to create logs for the developers.
Sometimes, when they try to improve something, something else goes wrong. You just have to be patient with them. After all, they’re only human.

Is it mildly inconvenient to open the mail app and wait a few seconds for the messages to load? Yes.
Is it also mildly inconvenient to open the mail app on my iPad to sync the messages? Yes.
Am I going to let it get me bent out of shape and effect the rest of my day? No.
Getting so mad over something so trivial is a choice you make. It’s just as easy to choose to not let it effect you so deeply. Once the developers find the bug, they’ll squash it. Until then, I get my notifications and I can red my messages. Not such a big deal.
