Hello:
I have migrated a site from J3 to J4 that uses K2 and the K2 integration plugin for Acy5.
I am using the updated version of K2 for J4 available on Github - seems to work fine.
However, the newsletters that pull in K2 content no longer work and K2 is not listed as an available tag in the editor.
Any suggestions would be really appreciated!
Thank you,
Alan
