Kobo's 6.0 beta firmware wipes reader annotations and sideloads
Kobo is telling affected readers not to roll back, warning the update makes missing data permanently unretrievable
Here's your one job this week: don't touch that beta update. Readers who installed Kobo's 6.0 beta are hitting endless loading screens, broken Libby syncing, and vanished annotations and sideloaded books. The part that should worry you as an author isn't the bug, it's the fix — Kobo says rolling back won't restore what's gone. If your readers lose their sideloaded copies of your book or their notes on it, that's not coming back.
Why it matters to you: If your readers use Kobo devices, a bad beta could permanently erase their sideloaded copies of your books and their annotations.
