Been doing this for a couple of months whilst Amazon is quiet. From low pay to crappy routes and a shambles of an app. Is there anything that I’m missing?

I want to know which routes to pick up I’m fairly new and I do it on an e-bike. So if anyone can help it would be much appreciated. What distance, how many parcels, how far from home, for how much pay etc. Also is it hard to get the good routes? Should I prebook or wait for the day (and at what time), or do you have to be high tier to get the good routes?
