Hi, thanks for your response!
Since I posted this, it seems to have resolved itself, but I wanted to answer the questions in case anyone in the future has this issue and sees this post.
I used Google to search for a video, and from there was brought to a Tik Tok Discover page, but still in Safari. From there I was trying to tap on the video and watch it, and it kept opening the app store, even though I had already downloaded Tik Tok and restarted my phone after installing it.
My iOS is up to date, 16.1.2, and I had just installed Tik Tok so I assume that was up to date.
I restarted my phone one more time since then, but had lost interest in the video and forgot about this until today, tested it out and it did work so I came here to respond. Not sure how it fixed itself, but I had just installed TikTok so maybe that was why? I just figured a restart would have resolved that and it didn't initially, which is why I posted.
All good now, so thank you!
Thank you!
