Hello Colin,
Yes you're right that OVH does not support us yet! We are already in touch with them, so the ball is on their court. 🏓
We always approach businesses that don’t have us on their iDEAL list, and oftentimes we do it with the help of our awesome users who notify us! 🌈
We always take the first step in the communication process but ultimately it is up to them to decide to implement bunq and that is why sometimes it succeeds, and sometimes it doesn't.
For now, you can always send them a little nudge; there is no stronger voice than of our users (and their clients), after all! 💪
