"We've made the difficult decision to shut down the Plex Cloud service on November 30th, 2018," Plex said on its support page. "As you may know, we haven't allowed any new Plex Cloud servers since February of this year, and since then we've been actively working on ways to address various issues while keeping costs under control. We hold ourselves to a high standard, and unfortunately, after a lot of investigation and thought, we haven't found a solution capable of delivering a truly first class Plex experience to Plex Cloud users at a reasonable cost."
The company launched Plex Cloud in 2016, and the feature supported Amazon Drive, Google Drive, Dropbox and OneDrive. However, Plex faced technical issues when transcoding media from those services on the fly, as Variety reported, forcing it to end Amazon support at the end of 2016 and eventually dropping Plex Cloud altogether.
While Plex says it's "super bummed" about how the shutdown will affect Cloud users, it plans to focus on adding features while improving its core service. Recently, Plex added podcasts (and later offline playback). Last year, it introduced a DVR function for live TV, with a scheduling feature arriving on Apple TV in February. Plex confirmed to Engadget that the Plex Cloud shutdown will have no impact on the DVR service.
