Used to work at Citrix for three years as a Product Manager. I empathize with most everyone's experience that they shared- at the tail end of my tenure, the company prioritized the sales teams over the engineering staff and unfortunately it showed within the product.
I think when set up properly, Virtual Apps and Desktops is killer for having good access to desktops and at the moment is a good extension of Azure Virtual Desktop. However, it did feel like we were running the product with a skeleton crew. As a result, documentation fell by the wayside along with other matters. I guess complete PE takeover of this sort of company is inevitable.
