Description
What happened?
Dear all,
I have developped a Winforms Application using the Webview2 widget.
Over the time, I figured out that some device where I deployed the app was having issues after an auto-update.
The scenario is always the same, the evergreen updater try to update ( check out the logs) and after I suppose a fail ( I can not interpret the exit code : 62).
My app won't work until I reinstall manually the widget.
How to work around that ? Because my appplication is running 24/24 and deploying device after device make this problem more critical.
An important point is that the targeted device can be connected trough 4G which makes the connection likely unstable. Are there auto-retries download implemented ?
