I have Cam Plus Lite and with the latest app versions am unable to filter by Person from both the Events page and the Filter page. The problem is described here: Unable to select event filters. Android V2.44.1 (326)
I have submitted diagnostic log # 1140662.
Someone else has posted a screen recording of the issue on the other thread. If it would help the techs research the problem, I could send a screen recording too - if so, let me know who to send it to and if there is any size limit.
