4 years ago While not possible through the app itself, newer versions Android allow you to adjust the behaviour of notifications e.g. whether they are shown silently or make a sound. You can find the settings under Apps > p!n > Notifications in your Settings-App. Or you can long-click p!n's notification and then - depending on your version of Android - select more settings or a small info icon.
On Android 8.0+ you will see two so-called Notification Channels labelled Newly added notes and Wake up alert instead. You should leave them enabled in order for p!n to work properly but when you click on their labels you can set their behaviour. Snoozed pins are pushed to the Wake up alert channel, so you could set Behaviour in this channel to Make sound. Modifying Newly added notes on the other hand will only affect notes shown for the first time.
I'm sorry for my late response and I hope this solves your problem.
I find it very easy to forget about a snoozed note simply because the notification doesn't make a sound.
