Session Recording Privacy Settings - Saving fails with free plan

Hi,

I am using the free plan of heap. This plan offers a recording of 10k replay sessions per month.

When I try to save the privacy settings for replay session recording, it shows an error. This only occurred since the demo period of unlimited session recording came to an end. I seems, as if it was related to the free plan.

I already tried to contact them, but since I am on the free plan, they do not offer any case specific support. I recieved an automated email with several suggestions. I tried all, but did not find help. This is kind of a stuck situation now, while I want to change the storage behavior as soon as possible, expecially the pages scope. 

Does anyone know anything helpful how to change these settings?
Did anyone experience a similar error in free plan?

Thank you!
