seeing AI problem with automatic reading on my iphone 13 mini

Hi,
For a few months now, Seeing AI no longer automatically reads the contents of a document on my iPhone 13 mini.
You have to take a photo and scroll through the result, which is much less convenient.
I restarted my iPhone and reinstalled Seeing AI, but nothing works.
I'll try contacting the developer, but I wanted to post here first to ask if other people with the iPhone 13 mini or older are also having this problem.
Perhaps the 13 mini is considered too old to handle auto-reading.
