More of a warning than discussion, a few people within my team updated chrome to the latest version, since then the deployment button is missing when deploying a machine in vRA
FOUND SOLUTION HERE:
Straight forward and no work arounds!!
Good luck !
Latest chrome update and the submit button is back for me.
I just noticed that the submit button was back when I requested a few deployments recently. My google chrome version was updated to Version 76.0.3809.100. We have not applied any of the patches.
