There have been some bugs which Zuora support has been unable to fix until now. For example, when we initiate sandbox refreshes, access of users who are only in the sandboxes gets wiped off, forcing me to recreate their accounts from scratch, although their entries exist in Zuora One ID, creating confusion and manual work. It has been a year and a half since this issue arose, and I believe it should have been fixed by now, as it is a significant problem when kicking off sandbox refreshes. Additionally, we faced issues with new payment method types rolled out in Q1 2025 that created confusion as they reflected under users' names, which should not happen.
