My smart plug, which can't be found since the app update now cannot be found on the  link to smart plug forum, I'm being advised it is a bulb!!

Anyway....since the app update my plug would work turning my lamp on and off at the same time as always, but was appearing offline and I couldn't turn the lamp off and on manually, which I previously could. Removed device but then can't re-add it. Have uninstalled app and tried re-adding the plug but it can't be connected. Help please!
