Our engineering team has identified an issue with the latest release of Point of Sale for iOS (version 4.82) that's causing the app to crash whenever it detects an unsupported printer on the sellers' local WiFi network. To resolve temporarily, sellers can disconnect from WiFi or turn off the unsupported printer. We've submitted a fix to Apple and the update resolving the issue will be available once their review is completed. Sorry for the disruption. We'll return with another post as soon as we have additional information.
