Please note, the developer account is an OLD account (old price list).

1) When app is republished to a client with an old price list account:

All seems to work as it should...HOWEVER, when using the "Copy Data" function in the Developer Zone (client side) from the earlier version to the just installed updated version, all looks fine on screen, but in fact NO DATA was copied.

2) When app is republished to a client  with a new price list account:

After installing the updated version in the Developer Zone and the updated copy of the app is available at home/dashboard of the client, the Developer Zone on the client side remains saying "Update Available". Yet the "Copy Data" function is not available.

3) Now using a NEW Developers Account (new price list account):

None of the (new) applications made as admin/owner of this account do show up on the Developer Zone. So in other words, they cannot be published to clients or the marketplace.

Please help.

Cheers,
