Bug description

Trying to link my laptop device, from my Android phone I go to Settings > Linked devices and press Link a new device. A dialog appears informing that Before linking, confirm it's you , asking to enter my phone's lock to confirm. I press Continue, enter my phone's PIN (PIN is correct, I know because if I enter something deliberatly wrong, it says Wrong PIN), validate and then nothing happens, back on the Linked devices app. page, without an error message...
