Unable to install Simple Gallery Pro

Tried to install Simple Gallery Pro from Simple Gallery Pro | F-Droid - Free and Open Source Android App Repository onto my Android phone but download fails with message:
The requested file was not found. https://f-droid.org/repo/com.simplemobiletools.gallery.pro_361.apk.

Have installed other apps fine. Can someone please advise and/or fix. Thanks,

Your app index is old, did you enable autoupdates on Wi-Fi and mobile data?

Pull-To-Refresh the index, latest is 364.

Thanks for the quick response. I have updates allowed on wifi and data. I thought repository was updated as had updated check for updates but seems this was the problem. All working now. Thanks.
