I just got octopi 0.16.0 installed on my pi3 b+ and running fine. I added a Adafruit 3.5 TFT and that also is working. I installed your OctoPrint-TFT. When I send a print to my MK3S via Webpage for Octoprint the TFT switches to Status screen and just seems to not update. Right now shows file, Elapsed time: 2m59s (never updates) and tools and bed temps (which don't seem to update)
On bottom of screen I have Print - Pause - Stop - Back.
If I press them nothing happens.
