Thanks @BlakeRichardson but I did try to put 4 as minimum, same results.
I don't think they give support to free account 🙁 I have a very small business and 12 devices.
what I don't like (because I used to have paid services before) the result is the same... you have a bug, they can't help you, it's always on the users side... so I ended up paying and still not getting thinks fixed !!
I'm going to post a issue I found about contact psw settings... once it was push the 1st time, it work.... but never go edit the settings, because Meraki can't send the psw to the device after, it will always failed... I was on the phone with Google for 2 hours and we found out that it was on the MDM side, not the iPhone, not Google...
did test with a generic CardDAV server, work No1... edit, push it back..., can't get it to work any more... create a new profile, push it... well guess what it work the 1st time !!
