ICloud sync not consistent between machines

I have two macs and one ipad pro. Previously I used Dropbox sync and change to iCloud sync when it first became available. I sync four databases which are about 57GB in total. To date it has worked flawlessly.

All of a sudden, one of the Mac’s has all the DB’s and appropriate folders but one mac and the iPad is missing three folders in one DB???

How do I go about getting the three missing folders back on to the Mac and Ipad?

Do I stop sync and clean out the iCloud DB copy then restart sync???

Please advise.

Thanks

It’s quite possible iCloud has stalled (and yes, that can and does happen occasionally). It’s best to start a support ticket so we can look at the logs.
