When you tap the “Reload” button in the android app, what all does it reload? Also, when do users normally need to do this?
The Android app is a thin container which uses a version of Chrome to render a regular website. The reload button tells Chrome to reload the website just like pressing F5 in your desktop browser.
There aren’t many valid use cases for end users to reload the app. It could be useful if the user dismissed the modal that pops up when a new version of the app is available. It’s also possible to hit a serious bug in core or configuration code which breaks the regular replication which can be unstuck by forcing a reload.
Mostly the button is used during development and testing.
