Hi. This used to work fine not sure what happened. Emailed support and they said to submit a bug here. In Kagi assistant on edge browser for Android (I know I know). When you select the text box the android keyboard overlays the text so you can't see what you are typing. I've attached a short screen recording of the problem. Thanks. Let me know if you need more information.
When you tap the input box to type, the keyboard should come up but not overlay the text input area so that you can still see what you are typing. As is normal for any other input box on a mobile browser.
