This can happen on any theorytab (and can even happen on the ‘popular chords’ page), just click anywhere on the page while the theorytab is loading and you’ll get this error message even if you’re connected to the Internet:
@Vaz123, thank you so much for reporting this. I honestly can’t thank you enough. For the past six weeks, I’ve been occasionally noticing that theorytab pages don’t load but I couldn’t figure out a cause. Most of the times I noticed it from my phone where thumb scrolling is such a natural thing, I was clicking way more often there during the load.
I have not fixed it yet, but I can reproduce with the click on my phone and desktop so I’m confident I can get to the bottom of it.
Again, major pat on the back for this one! Thank you!
