The Flic app is the only way to setup your Flic buttons and the app has issues. Their in-app customer support chat is a nice feature but they don't respond to your chats unless you email them through the website asking them to respond. I understand the developers and customer support are busy but I once had a message to customer support that went unread and not responded to for 34 weeks. The least they can do is read my message and let me know they'll get back to me. I have an active conversation with support in the app that I've been waiting 5 days on a response.
