External Keyboard isn’t recognized at review for Apps on AppStore

Only when I try to input a review for Apps on AppStore, the external keyboard doesn’t works.

The external keyboard works with iPad and any APPs I have.

If I turn power off the external keyboard works with board, I can continue inputting the review.

Maybe it is responsible of my external keyboard which is not the Magic Keyboard, but it might be undesirable effect caused by AppStore or iPad OS 26.7 .

I can write a review for any Apps, but I have not found any review area for AppStore.

So, I would like to share this phenomena to someone. I flow this letter in the bottle to the sea. May the letter reach to you.
