The latest update 😩, please look into whatever is going on,it hasn't worked properly since the update. Frozen on the main defender screen and a star on the side that does nothing when you try and access the tools section,was great,now I'm wondering why my reply from them is we're offline,and that's the reply I get.."PLEASE FIX THE PROBLEM"AND BEWARE OF THE LATEST UPDATE!!! Are you going to be offline indefinitely?

Last update seems to have broken the home page entirely for me - I just get the purple screen with the name of the app on it, and a (non-functioning) menu at the bottom. I can still do things through the notifications toolbar on the rest of my phone, but only the ones that were already programmed in. Any attempt to return to the home screen has the same effect. Granted, I don't have much room on my phone, at all, and none can be added (cheap Walmart trac-fone), so that could be contributing.

For some reason I started getting pop-up ads for dfndr. They popped up at random times. In the middle of texts, emails, everything. So I installed the app and ran the checks and fixes. Still getting the pop-up ads. Most redirect to this app on the play store. Absolute RUBBISH!!!! You give us pop-up ads that direct us to your product, then the product does nothing about the ads that IT caused. I guess it's a way to get people to pay for service... Ya know, like ransomware.
