Just finished my first oil change on my 2021 900. Upon removal of the old filter, examination of the bottom of the housing revealed pieces of dark grey rubber-like material. I'm thinking maybe it's excess gasket-forming material (e.g., Permatex). I can confirm that it is NOT part of the old o-ring nor part of the seal on the bottom of the old filter. Should I panic? (The old o-ring is partially visible in the image, for scale).
