If you have Cubex connected but the Sync with Cubex button isn't available, this could simply mean that your settings need to be changed.

It means that Cubex is setup correctly and fully connected to your Smart Flow account. In this case, a patient could be created and the information about the patient will be pulled from Cubex.

2. It is missing/absent.  
Such cases could happen due to the following reasons (you would need to check which of the below is applicable):
