How often does Epic sync the servers?

[Abigail Watson]

Hi everyone,

Does anybody know how often Epic re-syncs its servers?  I have been struggling with debugging an invalid_grant error; and went so far as to set up a half dozen instances with different combinations of confidential/dynamic/persistent/rolling; and it's been two days now, and some of them still have invalid_client messages.  Do they only deploy new client instances once a week?
