I am using a OnePlus 3T and have experienced the problem of not being able to select groups when sending an email. The groups are all set up on my gmail account and worked on my previous android device.
Following your solution, I selected the contacts app but the contacts menu only has the options Groups, Spam and Settings.
If I select Groups, I get a list of groups for each of my gmail accounts but there are no check boxes to select particular groups.
You can create an email and send to any or all members of your distribution list by going to:
->Contacts
->select Group (look on top of page)
->select the group to distribute email to
->select More (look on top of page)
->select Send email
->select individual contacts or "Select Contacts" for all.
You're welcome.
Now, if anybody can figure out how to *forward* an email to a distribution list I'd be forever grateful.
Thank you
Again, this isn't universal for all devices. Not all address books have the "Groups" tab you refer to.
It's not supported by stock Android, so it's not helpful to most users
WTH - We assigned Groups to our Contacts for a reason. Some ***** decides it's not necessary to be able to use the GROUP feature. I'm pissed - put it back! When we have so many Contacts, we have to find a way to locate what we're after. You invented features, they're still available, we need to be able to access them!
