Can you switch patches from within OwlNest? You should at least be able to select a different patch for the first patch slot.
I've also had problems where switching between patches using the Owl's push-button doesn't always work; this is most likely a software issue however, not a hardware issue, which means any such problems can still be fixed by the Owl team, and they will appreciate detailed bug reports.
It's worth bearing in mind that much of the Owl development focus until now was on hardware development, and much of the software is still in an early stage; I expect this will improve significantly over the course of the year. (I also think it was the right approach of the Owl team to prioritise their work. Fixing hardware problems after the devices have shipped is significantly harder. And of course both hardware and software development take a significant amount of time to do well, it's quite easy to underestimate how long it takes to build a great product.)
