Only One Deep Research per Thread?

Hi there,
I was hoping that this is only a temporately issue, but it seems, that is still only possible to have one Deep Research within a thread. This is really disturbing my workflow, where I build up information in one thread and have various Deep Researches on the same matter.

With the current situation, I can’t see the value of the PRO Subscription anymore.

Is it intented this way, or is this a bug?

Thank you for your support, very much appreciated,

Holger

Hi there, anyone taking notice of my request? Best, Holger
