Scanning barcode malfunction

Hello, I’ve used CM for over a year and love it. I’m a paid subscriber.

I went on vacation for 4 weeks, didn’t log my food, came back and all of the sudden I receive this message anytime I try to scan a barcode:

”This device is not capable of....”

Well, I’m using the same device (iPhone XR) that I’ve used a million other times to scan barcodes with no problem... so what is happening?
 

its driving me crazy. Thank you for any assistance you can offer.
