QR code scanning problem

• No issues when scanning printed QR code
• Scanning QR code on the phone screen failed to scan at 2 different merchants
• There seems to be a workaround for the scanning issue by toggling between pay and receive. This workaround did work in one instance but this could be just a coincidence
• Another possible bug when making a partial payment: payment failed when trying to spend all of the remaining balance with an insufficient funds message

I didn't have too much trouble because I spent all of the digital BerkShares I had, but I did run into difficulty at Indian Line Farm and Off the Shelf Farm, when I tried to scan the QR code from their phone screen.
I have an iPhone SE.
I had no trouble with my first purchase, which was at No Comply Foods. They had the QR code printed out. That also worked well at Berkshire Mountain Bakery -- they had it printed out too.
At Off the Shelf and Indian Line my phone would not scan their phone. It didn't even try to put the little yellow brackets around the QR code. It seemed like I didn't register. We tried to cut down on glare on the screen, to no avail. When this happened, I wanted to be able to come at it from a different angle, and I went to the "Where to Spend" option and looked up the businesses. It was too bad I couldn't just choose to send them money from the Where To Spend section of the app.
When I went to Berkshire Mountain Bakery, Dennis told me to try toggling between pay and receive if that happened to me again. Later, I went to the Coop, and the pay/receive toggle worked. I only went to 'receive' for a second, and then went back to 'pay' and it worked. However, there was a brief other bug at that point -- I didn't have enough money in my digital wallet for the full purchase, so I tried to do a partial payment of 89 B$ (the balance I had remaining in my wallet). However, it said that I didn't have sufficient funds in my wallet. So I ended up lowering the partial payment to 80B$ and that went through.
