Amazon fire stick update issues

Just had an Amazon fire update that has messed up both of my fire sticks and my Amazon fire. Has anyone had similar issues? Any suggestions?

I have three Fire TVs. After the 5.0.5 update, I have already have had two issues. First, the controls stopped working. I had to remove and add the batteries, and restart the Fire TV. The other time, the screen went black. Needed to unplug and plug in another Fire TV. Didn’t have these issues before the updates.
