I am a newbie to publishing Smartapps from the Github repository, so forgive me if this is a stupid question. The Smartapp was updated in Github since I first published it in IDE for my use. I have updated the code in my IDE and republished it with that new code, but do I have to do anything on the Smartthings app on my phone to make sure it is running the new code?
It will start using the new code automatically, but depending on what changed, you may need to open any instances of the SmartApp and just click Done to re-fire the installation portion in case code updates were made there. This also tends to be helpful for time-based SmartApps to fix scheduled task issues.
