Web page launched from QR code widget closes when switching apps
Today I had to take my son for a COVID test. At the test site you are asked to scan a QR code which takes you to a web page where you fill in some personal details. After completing the first page of details the website then sends you a text message with a verification code for your mobile phone number, which you then enter into the second page of details to complete the process, after which you can get tested.
I scanned the QR code using the QR widget, filled in the first page then received a test message notification, but when I switched from the web page to the text message the web page disappeared and I had to start the process all over again. The next time I scanned the QR code using the regular camera, and the problem did not recur - the web page didn’t disappear when switching apps. I seem to remember having the same problem with apps closing when I’ve used the QR code widget previously. Any thoughts on why this might be happening?
