I go to a concert at the end of this month so please fix the app ### 2/5 — Firmware (null) ? *2022-08-05* I am able to connect my light stick on another phone but not my own. My app says “firmware (null)” and I don’t know how to update it.. I think this may be the reason it is not searching for Bluetooth devices.. ### 1/5 — Help *2022-08-04, version 1.1.2* I also am having server version failure or something?!?? Will it be fixed before my concert??? ### 2/5 — Doesnt work :( *2022-08-01, version 1.1.2* I just brought my light stick and i know that its real but i still cant connect to it ### 1/5 — App Not Working *2022-07-30, version 1.1.2* The app right now is not working when I try to connect my light stick it’s says it’s unavailable and I try multiple times ( I really need help! ) ### 3/5 — Not working *2022-07-19* I’ve been getting ‘failed to import’ everytime I open the app. What else can I do? ### 3/5 — SOMEONE HELP?? *2022-07-18, version 1.1.2* I can’t seem to connect it but whyyyy???!!! ### 1/5 — Isn’t connecting to lightstick *2022-07-10* I recently tried connecting my lightstick but it won’t connect and on the main page it says something between the lines of server not connecting.

Someone told me to download the old app and it worked there so I'm guessing it's a technical problem with this app, please update it. Hopefully I'll be okay with the other app at the concert:) ### 3/5 — It’s not working for me :/ *2022-06-28* It used to work for me fine but ever since last yr, it didn’t want to for some reason connect anymore.
