Screen lock after submitting a Portal

Sorry if this has been reported previously. I’ve had a quick search but I didn’t find anything.
This issue goes back as far as Ingress 1.0, through [REDACTED] and now in to Prime. I never reported it on the original scanner because I didn’t expect the issue to carry over.
I submit a Portal, it successfully uploads and I get the confirmation email etc, all good. But then with the scanner open the screen dims after 45 seconds and locks after a total of a minute, as it would if it was just on a Home Screen. I can tap the screen to stop this but it will keep happening until I force close and reload the app.
It’s just annoying more than anything else and it does put me off submitting sometimes.
This has happened over a course of years, on about 4 phones in that time (all iPhones) and across years of iOS. Thanks
