Sometimes, when using the on-screen keyboard to type into a text field with VoiceOver on, I am unable to switch to the numeric keyboard. When I tap the Numbers key, it seems to insert a space rather than switching keyboards. This can make it impossible to sign in to a website or app if I've used numbers or special characters in my userid or password. I have reported this to Apple. Have any of you encountered this? As workarounds, you can connect a Bluetooth keyboard or access the credentials you've saved in Apple's keychain thingee, but if those are unavailable, you may be out of luck!
