The poster did not say that, when they went to GCKey to look for a message, nothing was there, hence my comment.While that's good advice, the issue that confuses almost everyone is that you get these messages telling you that you have a message that ... you do not have, because (most likely) they have not yet sent it. Probably just in a queue to be processed somewhere. Or if it is supposed to be in gckey or some other system, it is not yet there. Why? Dunno.
This may have made sense in the day of postal mail messages - we sent you a letter, please action it - in current context it is almost entirely nonsensical. Put the message into whatever system the recipient is supposed to read and action it, and only THEN send the 'please read your message' message.
Or even more simply, they could INCLUDE the operational part of the message that's in the message that they have sent you the message about (which just tells you to go and read the message that they haven't included, if I haven't confused myself by going too referential), instead of sending you this dance-of-the-seven-veils message.
I think this is a recursive re-entry message in computer science, but I never got to that part.
[This isn't you, @Kaibigan, I'm just pointing out that applicants/sponsors are confused for a reason]
However, I will say, in the course of our own sponsorship/PR application and the application of another couple where I acted as rep, we never had that experience. Every time when we were told there was a message waiting, indeed there was. We did get messages saying things like a status update, but then there was really nothing to see. Sometimes, signing onto GCKey, one would see an entry like "Last update: April 5, 2024." But there would be no sign of anything being updated. I took those entries to mean that the file was touched somehow, but nothing more than that.
