For the past week or so, HereSphere 0.10.0 has been mostly broken w/r to connecting to an online handy, uploading scripts, and in the rare event of a successful upload, the ability to skip through the video with my Oculus Pro. In contrast, DeoVR mostly just works (but DeoVR doesn't support SMB and I really prefer HereSphere). DeoVR previously had similar issues they solved by switching from Handy API 1.0 to Handy API 2.0. What version of the Handy API does the current version of HereSphere use? And is there anything I can do at my end to better characterize what's going on here?

HS uses Handy API 2.0. I tested it on my headset, and everything seems to work fine. Maybe try changing your Handy connection key, or restarting your network devices like your router?
