Cloudmagic EAS Zoho custom domain constant error.

Cloudmagic EAS Zoho custom domain constant error.

 I constantly get "The server has encountered and error. Please try again later" on refresh. The emails are actually synced when synced manually but you will always get this error.

Where is the cause of this error? Is this something CloudMagic need to fix or is caused by the Zoho implementation of EAS?
