The Importer Only Imported the First 100 Episodes of My Podcast.
This usually happens when your previous Podcast hosting provider limits the number of Episodes in your feed. Because Fireside uses your previous RSS feed to import Episodes, the importer is limited to what’s made available by the provider.
Unfortunately, many providers are guilty of this behavior (including Libsyn, Squarespace, and others). There isn't an easy way to overcome this limitation, but it may be possible to change this setting within the admin of your previous hosting provider.
Some Fireside customers have reported success by switching all Episodes after 100 into Draft Mode, running the import, then switching them back to Published, flipping the next 100 to Draft, and running the import again to get the next 100, until all Episodes have been imported. Other customers have re-created the Episodes within Fireside manually.
