I find on my browser, (when in the power meter mode), I often have to shift+refresh, or go back 15 minutes and forward 15 minutes to get the real time reading to be accurate. Changing out of power meter mode and back into it helps also. Agree, iOS client is best.
I used to be able to do the equivalent of “banging the television on the side” to make the browser work… Stuff that you mention like refreshing the page, switching from mode-to-mode or changing the time-period… (which in and of itself indicates that it’s not really working as intended)…
But now, I can’t even get it to work while banging on the side… Often, it displays no realtime information (either in the live meter or in the upper corner on other display modes), or the little dots that tell you that it’s “thinking” or “busy loading” displays indefinitely…
I used to be able to “bang on the side” to get it to work as recent as 2 weeks ago… But over the last couple of weeks, it has been behaving more poorly than usual…
