I know it might sound silly but it might be one of the possibilities. Maybe, the old version TMS settings are saved in the Ex90. When you purged the system and upgraded the TMS and tried to add the Ex90 again, it might be having a conflict with the previous settings and due to the mismatch, it is not showing up on your TMS. Can you try to take a backup of your Ex90 configuration and then restore it to factory default settings and try to add it again? If the provisioning still fails, we can assume that this is a software issue and we can check for the issues related with the provisioning.
Please try these steps and let me know if that helps you.
