There are multiple PDIs.

Instance (dev114239) opened from the "Start Building" button and
Why is the Instance (dev194238) opened from "Manage instance password" different?
I'd like to choose one or the other.

Hi @TAKEUCHI 

There is no way or i must say NO support how to avoid old PDI. Use the one which you feel is good or you are using.

Hi @Mark Roethof 

Thanks for the reply.

"I'd like to choose one or the other."  mean I don't want to reference an older PDI(dev114239).

Yeah I saw that in your follow-up reply to Atul. That was not in your initial question.

Unfortunately it is a bit like Atul is mentioning, there is no support on this.
What the reason for this is, cashing, or that the link changes after a few hours, scheduled, whatever: I have no clue. Do indeed see people facing the same posting this once in a while on the community.

Personally I never run into this because I only wipe my instance at every family upgrade and don't release it.
