Hey Catherine,
it was great meeting you in Rio. The Rio de Janeiro community was very happy to know you were here and meet with host from our community. The May 3 launch, so far, had a great positive response. It is so great that all our feedback is being listened and implemented.
Some feedback i can give you to further improve the tools are:
1) READ BY THE GUEST
this is a great feature that has been asked for many years and everyone is loving it. Great Job. This is a great improvement in the previous system.
Currently the tag "read by xxxx" shows below the text you have written. If you write another text the tag disappear from the previous text and appear below to the last text. This means that the tag "read by xxx" will just show on the last text written. In the previous text there will be no tags "read by xxx" nor time stamps on when it was read.
The current message system, show on the side of the senders name (guest or host) a time stamp when the message it was sent. I think a further improvement to the tag "read by xxx" could be showing a time stamp of when it was read in the same way is show when you write the messages. Adding a time stamp in each "read message" will give a context of when the message was read, than in a long reservation will be essential for example in resolutions. One thing is knowing the guest / host read the message 5 minutes after you sent it, another thing is knowing it just read 5 days later.
2) CUSTOM PROMOTION
It is great to be able to access the promotion in the app, and create new one. The best improvement of the may launch with promotion is that now we see the final price of the promotion in the calendar. Before we would just see the original price and an indicator that there is a promotion. But was very difficult to really know the price of that day. This is simply great.
I am sure you guys are working on it, but in the multicalendar still does not appear the final price after promotion, but still appear the original price with a green dot showing there is a promotion.
Another thing that I have noticed (and many members of the community contacted me about it) is that it was taken away the "edit promotion" button. This was a very useful tool to further give discounts in case of no bookings. You can still give it by removing the promotion and create a new promotion at a higher percentage discount, but it is not easy as it was before where you would simply click on "edit promotion" slide the percentage bar further and save.
3) CALENDAR
As I stated above the improvement of the calendar is amazing by being able to manage different setting by clicking on tools. Thanks for the great job.
One thing I immediately missed, is the rules set drop down menu that was removed. That was a great tool to be able to change or see in the regular calendar the rules set I have created and applied in the multicalendar. Many host who used the professional tools (not necessarily professional hosts) contacted me about this. People who have more than one property, usually activate the multicalendar and create rules set either for minimum days or for discounts etc..... Being able to see and manage the rules sets via normal calendar and app calendar, has been a request for long time, and it was included in the online calendar with great success. But was removed. That would be a great feature to include again in the normal calendar and in the app calendar. Today a guest contacted me asking if I would accept a 4 night reservations (I have a rule set with minimum 5 nights). On my phone I cannot change the rule anymore. Just on the desktop and on the multicalendar.

I haven't fully tested all the new tools, and will give further feedback along the way, but I can assure you it was a success in the community, and even "those hosts" the always had something negative about anything, are really loving it and posting great comments about the launch.
warmly
