Hey John, Thanks for filing this bug. I took a look and seems like onMetadata (code link) (caused by "GeckoView:MediaSession:Metadata" event) is being triggered multiple times because the artwork field in the metadata passed in is changing. This seems like the expected behavior to call onMetadata whenever the media file metadata changes. Are you observing these fields change as well?

Hello Cathy Lu,
i have attached the debug log from android studio, where artwork field remains constant but onMetadata method is triggered three time

Log:

handleEvent: metadatachange
handleMetadataChanged {"album":"","artist":"SabrinaCarpenterVEVO","artwork":[{"sizes":"320x180","src":"https://i.ytimg.com/vi/KEG7b851Ric/mqdefault.jpg?v=66c7ba44","type":"image/jpeg"}],"title":"Sabrina Carpenter - Taste (Official Video)"}
handleEvent: metadatachange
handleMetadataChanged {"album":"","artist":"SabrinaCarpenterVEVO","artwork":[{"sizes":"320x180","src":"https://i.ytimg.com/vi/KEG7b851Ric/mqdefault.jpg?v=66c7ba44","type":"image/jpeg"}],"title":"Sabrina Carpenter - Taste (Official Video)"}
handleEvent: metadatachange
handleMetadataChanged {"album":"","artist":"SabrinaCarpenterVEVO","artwork":[{"sizes":"320x180","src":"https://i.ytimg.com/vi/KEG7b851Ric/mqdefault.jpg?v=66c7ba44","type":"image/jpeg"}],"title":"Sabrina Carpenter - Taste (Official Video)"}

From the above log, you can see onMetadata method is triggered multiple times for same youtube video playing.
i have also messaged you on matrix to help you on fixing this.
