Nope. Happened to me just now. Opened some packs after midnight. Usually get my login streak packs then. No popup or packs. Got a popup just now, but no packs.
Definitely have seen timer issues as well, where overnight or after work I've only accumulated 1-2 packs. That one is a bit harder to say it's still happening since I did wake up to 6 packs this morning, but it wasn't a constant issue in the first place.
Update: I have gotten one pack since this post. It's more than 2 hours later so I should have gotten 2...timer is at 20 minutes.
