Thanks for looking into that, I’d like to live in a world where that popup never occurs. For the longest time Oculus VR and Steam VR plugins were enabled by default. (Only mentioned in the .uproject file if you disable them) I imagine Bridge may be on this path to being a ‘default plugin’ at the engine level.
Personally, I’d wait until 5.1 to see if it gets resolved. If it does not, I’d submit a bug report. (With a bug report there is a chance someone will agree that this is a rough edge that needs to be smoothed over and will create a JIRA ticket for assignment to devs)
Cheers!
