Hi,
Yes the problem is already reported to OutSystems, and with the next update (in 2 weeks) the problem will be probably be fixed.
The problem is introduced from version 11.10.1 upwards.
If you install version 11.10.0 client side debugging in your device will work.
Make sure if you install 11.10.0, to switch of the autoupdate feature of ServiceStudio.
Regards,
Daniel
