Public Beta 5 on iPad OS, iPhone iOS and Apple Watch are all working very well.
If you were thinking of jumping into the public beta on any of your devices I would finally recommend it.
Of course the usual warnings about installing a beta still apply.
I have four devices that are now enrolled in Public Beta. While I hesitated to install these betas on my devices, I ultimately decided to do so knowing that I had backups in place that I could perform if they were complete disasters.
I am going to give progress reports on each beta update...
