Hi @Intenso09
Thank you for your question! I recently came across an Option/Variant app that has a very helpful support team and with this app, I believe it can overcome the 100 variants limitation to let you A/B testing as much as you want. It could be worth trying to install the app and reach out for their guidance. The app link should be: Avis Product Options, Variant
I hope my answer is helpful!
Best,
Liz.
