As this has been mentioned before, I’ll skip too many details to keep it brief. I have NTAG213’s that have been written to using the NXP Tag writer app. This is working fine. The NXP Reader app is also working fine in reading whatever i write to the tags. The Background tag reading is however NOT working. There seems to be an issue, as others have reported losing this functionality!

Good grief Apple!! This communities page is very difficult to navigate!.. Now, back to the point.. I think i've solved this issue. The challenge appears to be with the writing of the tags. A lot of these tag writing apps have a "description" field. This is what throws Apple's background tag reading off the rails. If one simply does not populate the description field, a tag written with the proper stuff should work fine with background reading, however it is important to note that Apple currently supports a limited number of these things. This is documented in the developer area here: https://developer.apple.com/documentation/corenfc/adding_support_for_background_tag_reading
I've successfully written tags with a phone number, Facetime, SMS, email, URL's for http, https, http and https with www, as well as getting maps to launch with a properly formatted URL for a map location. I have not tried itunes or youtube links, though i don't expect there'll be any problems with those.
