We've discovered this overnight. It's seriously impacting us, issue seems to be having the number be optional. Broken key functionality in our widely used app. Really unnerving a regression like this can happen in a minor iOS release.

An update. As per other suggestions updating to 13.2 RC resolved. This isn’t ideal.

This is still a problem in b5. Are there any updates on this issue?
