Zoho Mail Subscription Downgrading Failed

Zoho Mail Subscription Downgrading Failed

Dear Zoho Team,

Please help. We need to downgrade our Mail Lite Plan from 13 users to 11 users (number of user to reduce = 2 users).
However, whenever we click the "Downgrade" button to continue the process, it always directs to this:



which indicates that the downgrading process failed.

Please help us to complete the process or guide us if there's something wrong that we can resolve immediately.
Thank you.
