Of 12 DMs I've initiated in the past 4 days, there were 2 confirmed undelivered and 1 with no response (that user isn't super-active so it's possible they just didn't see it).
I used Gossip to send all of these, which somehow decides which encryption standard to use before sending. Not sure how it does it, but it seems to work around 80% of the time, which is way better than having me flip a coin 😂
