Yes, I would like to publish some lessons in the future somewhere. However, a few quick takeaways:

* The microcopy matters, a lot. We had a button stating "I've got a notification: read what you should do after getting a notification" (from the top of my head and freely translated from Dutch, we didn't have an English translation back then). This was part of a bunch of buttons on the main screen that all gave information. Some screen reader users got confused and thought that they had a notification. If you don't see the visual layout, it is not obvious that this is just a plain button and not a bold text in red that is giving you a warning. * In the same category: the app has a status text that says "The app is working fine" or "The app is not working fine". Visually, the error state is signified by an exclamation mark and styling that makes clear that this is a serious issue. However, in text there is just one word, not, to signify that there is a serious issue. Following WCAG, the info signified by the exclamation mark icon was available in text, so no text alternative was required. However, we gave it a text alternative anyway to ensure screen reader users were also clearly alerted that something is wrong. Same goes for the "all is ok" icon, we gave that one a text alternative as well to ensure users all is fine.
