Just installed my Weather Station, and also am not receiving “Alerts” on my iPhone 8, running iOS 12.3.1.
I checked the App, and verified that “Alerts “ for all three categories are “ON”. We had a Storm go through last evening, but I received no “Alerts “ for Lightning or Rain.
I am exceptionally pleased with the ease of setup, installation and performance of my new Weather Station. Now, I just need to get the “Alerts “ working .
I have sent an email to “Support “. Just wanted to post here as well.
