Nomination disappeared after editing without any message

I nominated a pokestop with the title "Hősies tiltakozás emléktábla" and placeholder description and support message. I got the confirmation email and it appeared in the wayfarer. I applied upgrade next, and then edited the description. After hitting ok, I wanted to edit the supporting message, but the nomination was nowhere to be found.
I saw a similar thread about it:
However, my nomination is not abusive and does not violate any policy. It is a plaque on the wall of a church.
I understand you have some safeguard measures, but if I get flagged by a faulty algorythm, sure the least you could do is notify the user? This is an extremely unpleasant user experience.
Plus, as a side effect, my upgrade next is nullified and I either have to nominate something (if the timeframe allows), or use it on an existing nomination that may not need it.
Comments
Nomination has been restored, thank you for that, but please consider notifying the user somehow.
Thanks for reporting and for providing an update. This can happen if your nomination or edit needs additional review on the Niantic side before being added to the voting queue.
I hear you on the notification piece, this is something that is on the list of improvements to the system that we're evaluating as we design our 2021 roadmap.
