@thecudes Hi!
Sorry to hear this, it would be very helpful if you could submit a Bluetooth Log so we can take a closer look of what is causing this.
First, recreate the issue by trying to connect a Flic, then in the top menu, select Flic -> Submit BT Log. Write "Stuck on 99%" as description.
Once again, sorry for everyone experiencing this issue! Hopefully a BT log will help us track this issue down!
