Travel Failure: Invalid URL - PLEASE HELP

Basically, everything to do with packaging a game in Unreal is an absolute nightmare.

So please help if you know the answer to this one:

Warning: Travel Failure: [ClientTravelFailure]: Invalid URL: /Game/Levels/MainMenuLevel

I’m getting this message when testing my game on Android and its now starting to be a proper pain.

So when I go from Main menu to Intro level where the intro video is supposed to be, it just refuses to go anywhere.

In editor, however, it works just fine but when testing, it leads to nowhere.

Please see below the blueprints and help if you can

Thats the output log below as well
