If you want to add an apostrophe in your channel title such as" Podbean's Podcast", do not add the apostrophe directly into the channel title box which will make the account unworkable. You can use ’ instead of typing an apostrophe. Remember not to put any spaces before or after ’. Take " Podbean's Podcast" for example, you would type: Podbean’s Podcast as the channel title.Then, click on "Update Options" button at the bottom of the page. You should be able to see the apostrophe after the page refreshes.
