Flic 2 suddenly not working with Shelly relays?

[peter 6]

Hello Flic experts.

I have a weird situation. I have a Flic 2 button that sends commands to my Shelly relays through my hub. 1 press on the button toggles 3 Shelly mini gen 4 relays. It has worked flawlessly for months, but all of a sudden, it stopped. I have a double click command on the same button that toggles a Shelly plug and that still works. I can see in the app that the button triggers because the button image in the app reacts when I push it... I have tried deleting the button and re-adding it to the hub without any luck. I have also tried resetting the button by taking out the battery, but I can't get the battery out because I can't twist the cover off....

Did Flic or Shelly update something or do you have any other ideas why this is happening?

Thanks in advance for any help.

Best regards

Peter
