Downloaded to my phone, iPad and also downloaded the new OS for my Mac laptop.
There are a few things I will have to adjust to. I run the web page for Facebook and not the Mobil app on my iPad. I can no longer post pictures so had to download the Mobil app. Only use it to upload pics and then use the web page.
There are more adjustments that can be made to pictures....nice. Better spellcheck.....doesn't automatically make a change...putting who knows what word in...
Seems to work more like my laptop than it did before software upgrade. In about a week, it will all seem the norm, I'm sure. Really lots more to learn, just getting started.
