Issues we noticed as fixed:

*GO Plus / Gotcha should properly connect on most Android phones with this release. 0.109.1 fundamentally broke the connectivity on all of our test devices, and 0.109.2 restored it perfectly.
We can’t say how long it stays connected, but at least it’s connecting again.
*Friends list scrolling has been improved, not in a major way, but still quite noticeable.
The list still loads the next page upon reaching the bottom of the scroll container, and it still takes some time to load.
