Technician can only view his own request, not those he is assigned to

Hi - I have created a new technician. I have Associated him to all Sites and Associated him to all Groups. I have assigned him to a role of 'Service Desk Technicians' which gives him full permissions to all types of tickets. Service Desk Technicians are allowed to view 'All'

I have assigned 19 tickets to him. Nonetheless, when he logs in, all he sees is the request panel and within the request panel, he just sees the 1 request that has him as the requestor. He cannot see any of the tickets assigned to him as a Technician.

When he searches on one of the 19 tickets assigned to him, he gets error 'Request does not fall under your permitted scope. So you are not authorized to update the same.'

Any help would be appreciated, Thanks!
