Hi , I have been using Hook since March 2017 in India and working till now. I have two groups with two and three devices, lately since three days, my groups does not respond properly, one or two devices does not respond as required either ON or OFF, through the App as well as IFTTT. Checked the individual devices, each device is functioning well through the App. Restarted the hook and deleted and added groups. There is no difference. Any pointers is appreciated in advance. I have read the announcement regarding improvements in API and groups performance, probably it is since then my groups are not responding, Thank you!.
