Answer 1

the current release has maximum of 500 tables in sync group. also, the drop down for the tables list is restricted to this same limit.

here’s a quick workaround:

script the tables you want to sync

create a new temporary database and run the script to create the tables you want to sync

register and add the new temporary database as a member of the sync group

use the new temporary database to pick the tables you want to sync

add all other databases that you want to sync with (on-premise databases and hub database)

once the provisioning is done, remove the temporary database from the sync group.
