Adding xml feed from another instance to a rss reader

Hey all, looks like I added this question to the wrong group originally and was pointed here.

Basically trying to add feeds to a RSS reader.

Originally I had no problems with feeds on my home instance (lemmy.ca) but this morning no longer works.

Overall would like to add feeds from any subscribed community but seems to be hit or miss with a join lemmy prompt. See original post.

Any ideas or is it just a feature that needs some work at this point in time.
