Hi @magnetic_Daisy8312 ,
Thanks for the detailed report, that's helpful context.
A few things would narrow this down: is the user on Windows or Mac, and is Acrobat deployed and licensed through the Adobe Admin Console with Named User Licensing? Also, does this happen right after the machine starts up or right after the user signs in, or does it happen randomly throughout the day, regardless of how long Acrobat has been open?
The pattern you're describing, where the error clears after retrying rather than being permanent, points toward a licensing entitlement check that's timing out or racing with the network on the first attempt, rather than the user actually lacking the license.
Worth checking on your end in the meantime:
Confirm in the Admin Console that this user is still correctly assigned to the right product profile with no pending sync
Check whether this happens only shortly after login or app launch (suggesting a startup timing issue) versus at random points in the session
Have the user fully sign out of Acrobat, close the app completely, then sign back in, rather than just retrying the merge within the same session
If you're using any device-based licensing or a shared/VDI environment, confirm the device itself has a valid license seat, since that error can also appear when device-based entitlement hasn't refreshed yet
Let us know the OS, licensing type, and whether it's tied to app startup timing, so we can isolate the issue further.
