Bug description

Stickers sometimes to not arrive on the other end, showing omly a "retry" button no matter the platform the recipient is using. Sometimes this can happen per-device, and is not consistent, but happens often enough to be easily reproducible.

Steps to reproduce

• send a sticker
• ask the recipient whether they can see/download the sticker
• see bug

Actual result: The recipient cannot see or download the sent sticker. Expected result: The recipient should be able to view my sent sticker.

Can I get a log from one of the receivers?

I have this same issue, happy to provide logs but don't know how.

Stickers that don't work for me (Honor Magic 6 Pro), work on a different android device (S24 Ultra) and on iPhone 15 pro max too.

Reinstalling doesn't fix the issue for me on the affected device so it might be account related instead, as the other devices are on different family members accounts.

Sure thing! I've asked a friend of mine that's affected whether they'd be willing to share a log, they should chime in soon :)

(fwiw the debug log I sent is after I sent a sticker, but also having received some)

@cyrneko asked me to take logs from the sending side (me)

A friend of mine also seems to have mentioned they couldn't see my sticker Waiting for them to confirm

@cyrneko In earlier issues of 7.17, there was a bug where sending attachments you had sent in the past (in this case, stickers) could be badly-encrypted. I believe that's what you hit. It should start fixing itself. If you're still encountering the issue when sending from 7.17.4 in a couple days, let me know.

FYI @cyrneko is the one receiving the stickers and it not working; not sending

[cyrneko]

thank you for the heads-up, @greyson-signal !

I'll update this in just a bit to see if the issue is resolved, and if so close it.

I've opened a similar issue on the iOS side a week ago (so longer than the attachment cache time I've read elsewhere) with the exact same symptom, could the issue be related? (https://github.com/signalapp/Signal-iOS/issues/5871)

Both of these issues seem to be Mac/hmac related, so there is a good chance they're the same issue, I'd say.

As an update:

I personally seem to have mostly all my stickers working again, but multiple of my friends which recently updated (to various versions, I didn't ask) now are sending malformed stickers.
