Gmail stuck in loading/sync mode?

[Android Central Question]

Can't get my email from Gmail. It's stuck in "Getting your messages"...."Waiting for sync" mode. Gmail worked fine earlier in the day. Tried all the recommended fixes. Nothing worked. I have a Samsung Galaxy s5 phone.

Welcome to Android Central! Have you already tried going to Settings>Apps, selecting Gmail, then Storage, then clearing its cache?
