Missing Install/Download buttons for previously purchased apps

[zxmn]

It no longer says "Install" (or was it "Download"?) for the previously purchased iOS apps, both on my iTunes App Store and iPad App Store.

I can see the apps from Purchased tab, and visiting the app page from Purchased tab shows the Install/Download button, but when I view the app from Top Charts/search result, it shows the price (or Free App).

Anyone else having such issue?

Update: They're back and working now.

I found that when I went to 'buy' the app again, it told me I already owned it and this update was free.
