Some months back I purchased it and it worked fine with my chromecast with google TV. Had not used since then, maybe a couple of times. Sadly today I wanted to show my wife some videos on the TV because of the screen size, but now it only sends audio, and the screen is just black.
In response to the developer reply, am not trying to cast from any app. Just want to show my own videos and photos from my gallery that I took myself. No netflix or anything. I also wanted to show how to reorder the iphone icons and modify some iphone settings, but I can not see anything, Not even the iphone screen as it was before.
Update 2: I did shut down, then restarted the iphone 12promax, same for the chromecast wgtv. It didn’t work. However, I deleted ScreenMirroringChromecast on the iphone, then repeated the shutdown/restart sequence, and installed again the tvmirror+ for chromecast. This time it is working again. I can see the iphone screen, gallery and the basic needed. Guess some garbage was there from ScreenMirroringChromecast cache and/or iOS updates.
