Troubleshooting
Load bar crawls
Shut extra tabs, clear the cache, and let the first load run on Wi-Fi.
Expansion animation stutters
Disable power-saving and close whatever's running behind the browser.
No sound
Confirm the mute switch is off; on iOS one screen tap unlocks the audio.
Taps not landing
Let the current spin resolve, or rotate the device and back to re-fit the grid.
