Same issue: window10, HD Homerun HDHR5-2US.
Live TV/DVR tab missing; Settings/LiveTV & DVR…need to setup DVR; Dont see HD homerun tuners; try to add manually with IP address. After adding requested info and continues to pull up guide, get error that DVR is already in use.
Long ago changed my Plex acct to another gmail and no longer have access to junktrashbogusemail, but can’t find a place to update my forum linked email…any ideas…I know this is not the place for this topic, however I can’t see anything sent to my old gmail acct.
