Feed Items or Posts Not Importing - Check the "Force full content" Option
If you are using Feed to Post with the full content import feature, try importing without it. This is the option titled Force full content within the feed source’s settings. Sometimes the full text service we use for the full content import experience issues, and in that case, the import would fail.
There’s a number of reasons this could happen, so firstly please confirm whether the original RSS feed provides the amount of content you need. If it does, do not use the Force full content option, there is no need for it and it can cause problems.
Should you require the full text service but it’s still not working, please contact our support team.
