I've been using Zoho analytics for quite a while. Every time I am adding a new table to my big query  data source in Zoho analytics I do several manual syncs until I get everything in place.

In the last few days I can not do the manual sync anymore and I'm getting the following message:

Sorry, your current plan does not support this feature. 

My questions are:

What have changed?

What do I need to do to allow manual syncs again?

Thanks
