First of all, we apologize for the inconvenience. When casting as a TV / monitor If you get a streaming error notification, we'll let you know how to fix it. The first thing you can do is turn off the power of the Chromecast completely and then try casting it. (Completely remove and connect the power cord) For other ways, follow the following solutions: 1. Delete an error-prone device from the list - > Press the long key for the device name you want to delete. (you do not need to delete the Google Home device list) 2. Please force the Promota app to shut down and restart. 3. Wi-Fi connection from smartphone to network connected to Chromecast/ WebOS TV ex) Name of the wireless network to which the Chromecast is connected: MYHOME Connecting MYHOME networks from your smartphone 4. Re-register your device by rescanning in the Casting menu in the Promota app (Press search again.) ※ For those who use iPhone iOS14 or higher, Settings - Wi-Fi - Click the i button next to the Wi-Fi name you are connected to - Disable Personal Address If it doesn't work out, please email us at admin@promota.net and we'll help you.

We now support casting to multiple displays simultaneously. For more information, refer to our blog post here . 1. Connect each display to its own Chromecast. Ie: If you have 3 displays, you'll need 3 Chromecasts. 2. Through the Google Home app, connect each Chromecast to your mobile device. To do this, make sure you're on the same Wi-Fi network. 3. Once setup is complete, go to the Signboards or Slideshows tab. Choose one and hit 'Cast.' 4. A list of available displays will appear. Tap the display you wish to cast to. 5. Go back to Signboards/Slideshows and cast another. Repeat until all displays are running Promota.
