Accidental weaning- do we go with it?

Hi! After a rocky start, my LO is now sleeping great in the Snoo. He’s 4 months actual, 2 months adjusted (preemie) and is sleeping 7 hours/4 hours, waking up once a night to feed. Snoo is on baseline almost the whole night.

We bought a used Snoo from a friend and it stopped moving 2 nights ago. The O rings seem to be the problem. However, our LO’s sleep has not at all been impacted. He sleeps just as well as he did before.

Should we go back to motion or just go with it to avoid having to wean later on?

Adding that we do plan to fix the Snoo either for our LO or for resale or a future baby. Thanks all!
