PushOK SVN SCC Not listing new objects

We are using PushOK SVN SCC Plug-in together with Ivercy 1.1.0.0 for
development in MS Access. Recently, we have noticed that objects created in
development machine 1 and checked into the repository are not identified
and flagged for on development machine 2. Contact with Ivercy support
indicates that problem is error in PushOK: "The API-Function required for
this frequently implemented incorrectly in the Provider. (Or deliberately
missing, but PushOK indicates that it is supported in it's capabilities
flags.)"

I am using Visual SVN Server 3.5 together with Tortoise SVN 1.9.3.

This is causing big problems for us since our developers cannot readily
notice and add new objects to their development machines.

Please let me know what can be done and how fast.

Thank you in advance!
