Brave on Chromecast TV

So bear with me here, I sideloaded Brave on my Chromecast TV, has worked fine for months, no issues.

Usually I navigate with a little controller, has a touchpad and when I need to type the on screen keyboard pops up and I can use arrows on the controller to select letters and all is well.

Only, I updated Brave recently and now when I use the address bar, I can no longer use the on screen keyboard properly. It’ll let me type one letter and then it’s as if the cursor is elsewhere and I can’t scroll through the keys on the on screen keyboard anymore. Pressing the arrow keys on the controller will just toggle through suggestions instead. Sometimes it’ll let me go through the keys on the on screen keyboard but I can’t go right, I can only go left.
If I turn off browser suggestions in the address bar it fixes the issue, but I don’t understand why it’s happening at all.

I know this is an unusual use case and Brave isn’t made for this but it has worked fine for months, so I’m not sure what might have caused this. I just wondered if there was a fix or possible way to diagnose it further. Any help please? Thanks

Just to update, the typing issue happens even with suggestions off. But for some reason I can’t go right on the keyboard with them off, while with them on I can barely type at all. Anyone know where else I can ask?

Anyone got any ideas please?
