Why is the shortest mail sync/fetching time now 15 minutes? I had mine set to only 1 minute before this update? Now my laptop and phone run out of sync.
I just typed the words “15 minutes” into the search function for you. This is the first result: Is 15 minutes really the new minimum check interval?
In short: it’s a restriction by Google. Using push mail is more battery friendly anyway at that rate.
