It's been a while that I dealt with it, I don't know what is causing it but sometimes when I go next frames especially on future forecast, it takes a second or seconds to load then next frames before it loads up. is this an optimization issue on my end on Website version or something with website, Especially once I go on sea layer it takes the longest when i have the grid values on. when i first started found ventusky I surely remember not having these issues,
