I am yet to be convinced that the latest version of 5.1.1 is worth installing. There are mixed opinions on this forum from people who have installed the November 16th version.
It looks like only about 10 people using this forum say they've installed it. There must be more.
Let's please see a show of hands as to how many people are using the November 16th version and if you are satisfied.
Updated yesterday and all was working fine for about 24hours but am now starting to receive texts hours after they were sent--this was the initial problem I noticed weeks ago. At least for me, this most recent fix, was not a fix.
