It’s a bit of a funny thing this treehouse app, because all of us on the sofi team use the app “DiscourseHub” to access the treehouse, however if I recall correctly, Android also created it’s own treehouse app for some pioneers a while ago - that was completely unbeknownst and unprompted by us!
I’ve just seen above that you also mentioned a 30min wait time for the bubbles to load! Even 2 minutes is 2 minutes too long for us, so love to get a screen recording of any delays here to see if we can’t make some changes to help 
Please feel free to email myself (alex@sofi.health) and Kirill (kirill@sofi.health) should you like to send any recordings there! x
