tiktok video share

When I try to share a TikTok video on messenger my recipient gets it the first time. But if I send another one they dont see it. Instead they see the logo TikTok-make your day. And don’t see the video I intended to share. Happens on my iPad and my phone.  I’ve tried clearing the cache, that won’t work. It shares my video only once, then it won’t share another one.
