Thanks so much for following up. Sorry for slow response.
Yes - I am definitely on .113 and security 05 Aug.
I am not 100% certain - but I would say this started with the upgrade to .113. Previously I could use One-Handed (and I remember that when I first got the phone approx 1 month ago and set it up, One-Handed was the default setting).
Strange not to have seen any MeToo in response to my post .. .. but if you can identify the problem and resolve it that will be fantastic! (I checked just now that the problem persists - it does.)
