I have been using Automate (the Hub) to manage updates; if something fails, or if I happen to notice a needed update before the automated one runs, then I try Update for plugins/themes from the Hub. ElegantThemes products fail to update at times, but sometimes succeed. But, UpdraftPlus is never successfully updated. I have to go to the WPADMIN for each site to update that plugin. This happens on multiple sites some of which are single installs, some are multisite installs; all are current WordPress versions; all are hosted at Pair.com, with some on a dedicated server with others on a shared hosting plan.
