Help! I went to sleep and the next day i went on my iPad air and now all of my bookmarks on safari have disappeared. I have force restarted it a few times but nothing happened. Please help.?

It sounds frustrating to lose your bookmarks! First, check if you're signed into iCloud and if Safari is enabled in iCloud settings, as this can help restore bookmarks. You can also try checking if there's a backup available in iTunes or iCloud that you can restore from. If those options don't work, consider reaching out to Apple Support for further assistance.
