If you are reusing previously created virtual browser profiles, your profile's emulated browser version may become outdated as time passes. You can upgrade the profile to the latest available browser version from the server. The exact target of the upgrade depends on the profile's current device, browser, operating system, and language.
This is necessary if you want to stay under the radar. Nowadays browsers are so-called evergreens. It means that they update themself automatically. Having a profile with an older browser version can become suspicious.
Simply select Upgrade profile from the profile's context menu on the dashboard.
Be careful, as this is changing the Base Profile of your profile.
