With the introduction of the new timer, the duration has been limited to 100 minutes. This is fine for groups working simultaneous. I really like to be able to have asynchronous meetings and collaborations sessions, lasting up to 4 or 5 days. In thes meetings, collaborators can work at their prefered moments, within the time limit set.
Please (re-)enable timer settings up to several days, counting down in days, hours, minutes and seconds.
