Shelf Life of a Summon

The free daily summons expire at the end of the game day if I don't use them because it states it on the pop-up when I receive those free summons. But what about other free summons like Rank As that are awarded as prizes or Rank Bs that are awardes from raids? Let's say I release it from my gift box and it shows up on my summons page. Will it "expire" at the end of the game day or will it stay on the summons page until I use it even if it's weeks later?

Thanks in advance!

I've had like 50 waiting for me before, so I don't think they expire, but I could be wrong...

I have had them last for days after they are taken out of the gift box. I think stuff only expires if it stays in the GB, once you get it out of there you are good to go.
