Telling people to download a completely new browser or software is the worst kind of suggestion to a problem that shouldn't be happening at all.

I typically have loading problems too, generally when I'm forced to clear cache after every update. Reloading the assets seems to take an ungodly amount of time and tends to fail for one reason or another. Although I've never failed to get into the game itself, I still tend to freeze up when trying to start a battle right after a cache clear.

I sometimes get around this by loading some of the assets before jumping into a battle. By viewing my squad page and loading their sprites in the Unit menu beforehand, jumping into a raid boss first, etc. Which sounds silly but It seems to work.

In the end you'll just have to keep refreshing until whatever is locking up the loading fixes itself. Clearing cache multiple times does not help since you'll just be forcing it to reload all the assets again.

The fact that this cache clearing caveat that's been around since the beginning of the Nutaku version and has only been getting worse with each update is frustrating.
