The Web interface use exactly the same method to switch channels ...
So there I'm lost ... if the tools works OK using the web interface then it should also work OK using the iOS app ...
I suppose you are doing the tests from the same device ?
Do you have anti-virus, firewall activated ? Try also de-activating this.

Best regards,

my decoder is a Sab unix solo. Reboot remains the same. Everything works when I use google on my iPad without the app. But that is not the intention of the app.
on the Iphone, the same problem.
But the problem came when changing a channel
Thanks

Reboot your Dreambox to see if it helps ...

Best regards,

Dear reader
I use enigma TV on my computer with the iPad and android-tv stick to the TV. On my computer, the picture is perfect no problem. On the iPad the image of a HD channel, was perfect until I changed the channel. The picture went black and I got the browser with my favorite channels. Now the app no longer works. Every time I start the app I get the browser and after a while the picture is about 1 second black and then I got the bowser again. I have reinstalled the app. With the same problem.
