Don’t have it yet? It’s probably us, not you. 

Features are released over some time to ensure things are working smoothly. We highlight features that you may not have because they’re slowly releasing to larger numbers of Insiders. Sometimes we remove elements to further improve them based on your feedback. Although this is rare, we also reserve the option to pull a feature entirely out of the product, even if you, as an Insider, have had the opportunity to try it.  


Please tap Settings > Send Feedback to submit your thoughts about this feature.  Choose I like something, I don’t like something, or  I have an idea. We look forward to hearing from you!
