So I am currently having an issue with TalkBack. It doesn't respond or speak to me whatsoever. No amount of swiping, using gestures, etc, does anything. In fact, when my little brother tried to use it to help me figure it out, the screen acted like TalkBack was off, meaning he could tap with a finger to activate icons. I tried toggling TalkBack (hold both volume buttons) to toggle it. The familiar chime indicated it had been activated. No go. Tried with Gemini, it said TalkBack had been enabled. No such luck. I'm not sure what's wrong. Any tips?
