I can't buy my ios one-time lifetime app for $5.99.
When I looked, there was no option to buy at all.

I only purchased a lifetime emby client key, but I did not purchase a one-time application on the ios side. I was looking at someone else's server.

Hi, did you try to play a video in the app?

Yes, I played the video, but I have solved the problem now, thank you

What was the solution?

It should be that it has been downloaded on the phone before, and I have purchased and unlocked the app with another Apple ID account. Therefore, it shows that my device can be unlocked and used, so the purchase option will not pop up.
Just buy it with another brand new phone.
