Has anyone had problems with this brand? I bought the advance for the 1st time on Monday. I started testing that same night. My result for that night was a blank face, so I tested again on Tuesday morning i got a blank face than that night I tested and I got a face that represents "peak" after that test the face symbol won't go away.. I wanted to test this morning but I couldnt the face was still on the screen??? Any way I could fix it... it will suck that I spent so much $$ for nothing 😤😣
