I have been using Messages+ on my Droid Turbo, tablet, laptop and desktop for 6 months. I have started having problems the past week or so. On my laptop, I can no longer use the app. I open the program and it asks me to enter my cell number for activation code. I enter my phone number, get a text message with the activation code. I enter the activation code, click done and nothing happens on my laptop. I get a text message saying my device has been activated but my laptop still doesn't load the messages+ app. If I click done again it says to enter a valid security code.
My tablet will at least connect but I have to activate it about every two days. What is going on?
