I don’t know if this behavior is desired or a bug.
When I send coins or make a trade and leave the app after a while the system message pops up e.g. pDEX balance updated. But this message comes always too early. When i click on it to get to the app, there still is no new balance visible. I always have to wait a few more minutes to see it. This is a litle bit confusing and should be changed. The message should appear once I can see the new balance in my wallet.
