I don’t know what happened, but my Continue Studying lessons disappeared! And a YouTube video that I had imported and had already finished studying also disappeared.
The lessons that I had studied recently disappeared and only things that I had opened a long time ago appeared.
This happened after a day when I was trying to open the application with very bad internet (about 3 days ago).
I may have had a similar problem two weeks or so ago. One lesson I had uploaded and completed just didn’t appear in “Continue studying”. Then I noticed a new tab had appeared, “Failed to import”, and three lessons I had imported consecutively the previous week were listed there. I could still find them through the search and within the course they were imported into, I was able to finish all three without issue, but none ever appeared under “Continue studying”. This never happened to anything I ever imported before or after, and the “Failed to import” tab is just not there anymore.
