It's simply price alerts on various coins where I'd like to buy more or take potentially take profits.
A lot of the time they do work but some definitely haven't shown up and I know their price has been bypassed as they've disappeared from my list of alerts.
My main issue is when multiple alerts are triggered (as is often the case as the market moves as one) it only shows me one in my notifications and there is no record on the app that I can find to show what other alerts have been triggered.
Don't worry yourself over price alerts because if the price of a coin didn't go up or come down,there will be no alert notification. The moment you have gotten any alert notification and it don't show up for easy access, why don't you login to the app to confirm for yourself.
If it is a wallet that you are talking about,then this depends on the type of wallet that you are using. I have a trust wallet that notifies me in any price change in bitcoin especially. What I do is that I will login and check other coins too if there was also a change in the price. Sometimes, the problem might be from your phone.
