This problem sometimes occurs when the IFTTT is delayed in retrieving information from the Prota.
If you have troubles retrieving your MicroBots on IFTTT, make sure that:
1. Your Prota is on, and the internet is connected.
2. All apps are installed and up to date, especially the IFTTT app on Prota Space.
3. If it's all set, try to make the applet again.
See here how to upgrade apps on Prota Space.
