This morning I noticed a light bulb routine did not work. Went to check within my app for an issue with the bulb. First thing I noticed is the app signed me out. It took forever to get signed back in. Once back into my account received an error message about not being able to update device list with an error code 3840. I have signed out and forced close the app multiple times. No change to the issue. I’ve restarted my phone. No change. I can receive camera notifications as well as see a list of recordings in the events. Checked my connected devices with my Alexa app. It appears there that two of my bulbs are off line. But the majority are still online but to be controlled. They are not visible within the wyze app itself. ![IMG_3782](https://us1.discourse-cdn.com/wyze/original/3X/2/a/2a266846c6e5f6faeb1af0debf9e190e9f4115a8.png) ---

I’m experiencing the same error. I sent email to Wyze support a couple minutes ago. I don’t have any helpful info at the moment, just solidarity. ---

Same issue here. Multiple forums about it already, along with Reddit. No idea what’s going on. Wyze bot says they’re tracking multiple issues but doesn’t address this error code. Tried calling from STL and says I’ve reached them out of business hours… not true. Something’s up. ---

Yes I ran into the same issue. What I also noticed is that all the cameras turned on with their red dot which prompt me to go onto the app to see what’s going on. But couldn’t connect to any of my cameras. ---
