Hi , how do I put my other devices on cover.

Hi bt390
 
Welcome to the Community Forums.
 
Well, WSA comes iin PC, Android, iOS, & OSX 'flavours' so looks like you need information on how to cover off the first two of my list, and will do that given that I am not sure what you already have covered.  Unfortunately, as far as I know there is no Blackberry version and not likely to be, either.
 
For how to install and 'cover' a PC please review carefully and follow the instructions in this Knowledge Base article.
 
And for Android please first review this Knowledge Base article covering making sure that you identify & download the correct Android version , as which you can use is defined by the license you have for the PC version of WSA.
 
For guidance on installation under Android please review this excellent prior post from one of our senior member @ which covers it all very well.
 
I should just point out at this time that you will need to have a subscription for at least as many devices as you would like to/can cover.  That is of course excepting the devices (android) where the recommendation is to install/use the free version of the mobile app.
 
I hope that covers it or at least gives you plenty to go with, and then if there are any gaps or questions then please post back and one of us will be happy to help you out further.
 
Regards, Baldrick
