An user reported a bug in version 1.2.1 which can cause ScadaMobile to stop updating tags on the main tab view after switching from another tab. The bug is mostly related to low speed connections or long latency devices, but can (rarely) happen with highly reliable local wifi connections too. The bug appears as blank space on the right of cells for more than 15 seconds when PLC data should be shown. Only version 1.2.1 is affected. Earlier and newer versions are not. A workaround for the affected version is to switch monitor off and on again. Version 1.2.2 includes a fix for it. We strongly recommend to download it.
