I think i figured out why it did not work for you. I tested the app on a couple of PC's and it didn't work on one of them either. I just updated the browser and it worked. It had been a while since that pc had even been turned on. So it makes sense the browser would be out of date.

I also noticed that some icons (emojis) I used on the buttons may look different based on the fonts you have installed/available. So some icons may not show correctly or at all (replaced with "[]" when not found). I am working on swapping to more common emoji that will show correctly for all.
Thanks for trying it again!
