I've noticed issues lately with the Timer function which sits in the Clock app. I use it regularly for my beauty business (timing treatment etc) but today I noticed when I set it up for 14 mins, checked approx 4 mins later it was still at 13 mins and 20 seconds and counting down. Like it had reset itself at some point.
I thought I was going mad so tested it again with 5 mins and sure enough around a minute later it reset itself to 5 mins and counted down!
I updated my phone on 1st - prior to 1st never had any problem but now I do. Not sure if linked? Please help!
