Anki deleted my card

Hi, i have a deck of 300 word and I consistently learn them in 5 days. l learn 2 - 3 cycle 300 card/cycle.
Today, when I look at the browser, they’re all deleted. However, when I looking at the browser in anki Iphone, It shows the 300 word. Therefore, i think that anki hide them. However, i don’t know how to see these card again.

It sounds like a sync issue. Make sure you sync your collection on Anki desktop and Anki mobile too.

Perhaps you have reached the daily limit?
