I have setup an outgoing Gateway Network Connection from the 8.0 beta to another existing 7.9 Gateway and the status page shows running and connected. However, I do not see the 7.9 Gateway tags in the tag browser in the 8.0 Designer. I have refreshed many times. I have two 7.9 Gateways connected and the tags show up in the 7.9 Designer tag browser.
We haven’t seen any issues with 7.9 tags showing in the 8.0 Designer. Just to confirm, did you setup a remote Realtime provider on the 8.0 gateway after linking the servers?
