Back gesture not working after 18.104.22.168 update
After the 22.214.171.124 update, the back gesture no longer works in the area where the keyboard is. You have to swipe in from the area above the keyboard in order to go back using this gesture. I can confirm this is not an Android issue as Samsung and OnePlus devices are both affected. Reverting back to version 126.96.36.199 fixes the issue. So something was messed up during the latest update. It's a bug. I have raised a ticket with Microsoft, but if you are also experiencing this I would urge you to do the same. It's extremely annoying and you end up typing random letters when trying to swipe in from where the keyboard is.
