I tried to submit a ticket to ask this question but I have not had any response in 3 days now.
I own a copy of Royal TSX which we renewed at the end of July. At the time I was fairly happy with Mobaxterm on Windows so we decided not to upgrade to the bundle offer but we got the renewal through for support for Mobaxterm and given my increased mixed OS use I thought I would ask how much it would be to upgrade to the bundled edition mid renewal to compare against the Mobaxterm cost.
Handled via a ticket now.
For anyone else that wonders drop them a ticket and they will should get it sorted for you.
