Printing issues caused by Android WebView update
Incident Report for Bizzon
The problem: Google released the latest version of the Android WebView component (108) on the 30th of November. This version changed how web pages are cached, causing issues with Bizzon printing. As Google Play automatically started upgrading the WebView component on devices in your hotel, your staff started experiencing problems with printing.

The Solution: We updated the part of the app that deals with printing to circumvent the new behavior of the WebView and released the hotfix version of the Bizzon app (v4.1.1.1) on Friday 16/12/2022.

The cause: Bizzon uses the Android WebView component to print orders, receipts, and reports. The newest WebView broke the compatibility with the Bizzon app, causing the previously printed document sometimes to get printed on another printer. For example, the order printed on a receipt printer would afterward be printed on a kitchen printer and vice versa. Because of the lower resolution of kitchen printers, the order on the kitchen printer would appear magnified or empty.

Since there was no warning from Google that breaking changes would be released, it took us some time to find the problem and fix it retroactively. We apologize for the problems that this has caused.
