Switched to Paddle earlier this year for other reasons, glad I'm not affected by this. Paddle is not as pleasant to work with as Stripe from a dev perspective but it also handles so much more that what I need to integrate is tiny compared to Stripe.
We tried to use Paddle for our company but back when we were trialling them they didn't even have a dev environment (their suggestion was to create free products in production mode and use those to test dev/staging). At that point I nope'd out of there and moved to Stripe.

But elsewhere they also still seem to recommend doing things involving your production site for testing purposes. That seems like it's probably a bad idea that could be risky if anything goes wrong and possibly mess up things like reporting and compliance even if everything "works".
