Regarding Twitter, due to the recent changes from Twitter API's end, and changing of the pricing plans, we have removed the source "Twitter" from the Pro and the Pro Plus plan and added it only in the Premium plan for EmbedFeed.
Twitter account feeds update in the Premium plan every 30 minutes. Twitter hashtag posts, are only available in the Enterprise plan, which you can contact us here
Feel free to let us know if you have any questions.
Thanks!
