Stuck in download mode / can't open a new session.
So iam using the metasensors for a research on motor control impairment and noticed that all my metasensors are stuck on 'download' with a red dot next to it. After hitting download over 10 times it doesn't seem to be possible to create a 'new session'. Upgraded firmware etc. rebooted my Phone (android) but nothing seems to help. Problem started after 2 sessions of 2 minutes.
