TikTok's new US owner has apologised to users for "disruption" after thousands reported issues affecting the video-sharing app.

Platform outage monitor Downdetector said it has seen more than 600,000 reports of glitches from US TikTok users over the weekend.

Problems flagged by people include videos appearing repeatedly on "For You" feeds, some content not displaying and new posts getting "zero views" - with issues appearing to continue for some on Monday.

TikTok USDS Joint Venture LLC, which now oversees the platform and its operations in the US, said it was "working to restore our services following a power outage at a US data center impacting TikTok and other apps we operate".

"We're working with our data center partner to stabilize our service," it added in a post on social media platform X.
