I have created one metadata profile having 2 text fields and one tag field, text field is saving and rendering on reload but tag is saving but not rendering on reload.
I have seen in google that it is known issue from 6.3 and they provided fix as well. We tried the same fix on 6.4 but not working, please check and do needful asap.
* Which exact/complete versions of AEM 6.3 & 6.4 did you try this on? Were those the latest versions on both AEMs?
* Can you also please share the exact steps in detail?
You can also log a ticket with AEM Support team to get this issue resolved/attended to, at the earliest.
Can you confirm if the below issue is on metadata profile form or tag values not rendered when associated to asset via asset's properties action?
