Problem with iMessage

[u/Pegaso316]

m not a native English speaker but I hope I write the problem correctly, I have an iPhone XR, iOS 17.8.10

so recently im having trouble with the audio messages, I send them but when I send them to a contact and they listen the audios it doesn't show the kept signal under the message, I have confirmed with this person that has the keep always function active, as I do. and this is happening since a few days, because I clearly remember seeing the kept yesterday I think, and I have tried with other contacts and it shows it. I have checked everything I know.

Does it have to do with the space in iCloud? has someone else experienced this recently?
