I have the same randomly ”forever loading” problem on mobile devices with THIS main ( meta dot Discourse dot org ) support forum and our ( gramps dot discourse dot group ) hosted site. It does NOT get stuck in a loop with desktop systems.
The Loading loop gives NO feedback of what it is actually doing. Maybe there could be a timeout feature that says ”still trying to to load xxxx”
There are a LOT of ”Loading” related posts on this forum… WAY too many to peruse. (Maybe you can develop an administrative tool to link duplicate issue postings & set a Preferred answer… with a collation in the search results. e.g., ”207 duplicate threads linked to the solution of ”forever loading” found for your search term ”loading” )
One that looked promising was a DNS failure that resolves when clearing cache & cookies. Although why mobile would suffer a DNS failure the doesn’t affect desktop is confusing. Since the ”forever loading” failure is random, maybe the DNS was just a convenient scapegoat?
