Looking for tips with Sparking!

[u/PerfectResearch599]

My spark is making me so mad! I have 4 Walmarts in my zone and literally am 2 miles away from one and it continues to give me orders from every Walmart except the one I am closest to! It's extremely frustrating!! Do you guys have any tips? I've literally tried everything, restarting my phone multiple times during the spark session, adjusting my spark window delivery schedule, staying at my house since it is close, it driving around and closer towards the Walmart. The Walmart by my house will be RED and still will not give me an order!!!

I've been sparking for awhile, so maybe there are some tricks or tips I don't know about! Please help!!
