Request for International Upgrades cannot be processed until after 31 March a new Bug?

[/B]UA Insider , can you please confirm this. 15 minutes ago,I called 1K desk to book an international Tix. I indicated to the agent once ticketed I would like to use my GPU since there was RN/R seat available.
I was told as of today,I will not be able to request international upgrades until after 31 March when the issue will be fixed, because both the online upgrade system & agents can see GPUs in my account,however cannot pull them.
It was Elite Houston call center Agent.
I decide not to go ahead with my booking of course.
Is this a new bug?

On Upgrade unrelated: On old United Site one could view Upgrade History. Will New United Site offer it or is that option now history?
