I don't use the SQ Remote, but the Automator app I use needed to be updated because the latest Firmware (1.5.408) and Foscam Plug-in (2.2) use a different device type for the camera, "urn:schemas-upnp-org:device:DigitalSecurityCamera:2".
Some people have had success getting their mobile apps to work again by changing the the "2" back to a "1", but this may cause other issues. To truly fix the issues, the SQ Remote app most likely needs to be updated to use the new device type.
