Using the Quest native SLR app and a lot of times I get a timeout error or the script just not being send to the Handy. It becomes more apparent when browsing videos quickly. I also see a lot of 'Handy connected' notifications coming up while the wifi connection of the Handy is up and running. I also had scripts continuing to play when switching videos a couple of times. I don't have any of these issues with other apps so I don't believe it's my Handy or Wifi connection.
In addition to the timeouts, I also noticed it takes a lot longer to send the script to the Handy compared to other apps.
