What does Installed app version mean?
An installed app version identifies the release currently present on a device. It can differ from the version advertised in a store or download guide, especially when updates are delayed, managed separately or installed outside a store.
Why it matters
Look in the app’s About screen or operating-system app information. Copy the value literally, including suffixes where shown. A download date is not necessarily a release date, and a file called latest does not establish the installed build. Version details help distinguish a new software fault from an account change that happened without an update.
