Two months since this ticket was opened and no response from support, but they close out any related bug report as "resolved". This is not very good support. I may have to cancel Realms subscription. I won't pay for a service without support when it breaks.
I also cannot download a copy of my realm. It completes the download, but then says "Level Import Failed" and "An error has occurred"
I have tried all suggested workarounds, except Windows. I even rebuilt my PS4 database. Internet is wired, high speed, not Wifi.
I disagree with this being marked resolved, as the original ticket is still open with no resolution, and my issue is not the same as the one in that ticket. On that ticket, the download was freezing. My download is completing, but then the import is failed.
If you do not want duplicate tickets, fix the issue.
