To be honest this a matter of convenience to me, I have simple App that I can test on two real devices. But, it does let me determine if it is fixed with two button clicks. So the issue really comes down to when a new release might come, I realise that is beyond your control, but I suspect the focus on the 9th of June has become all consuming.

No. Tested it this morning. I was hoping it was a Sim bug but I guess that was deluded. I guess we await 15.5.1, any hints when that might happen
