We keep getting reports and complaints from users that buy our apps but seem to be locked in trial mode. Receiving 1/2 reports a day. We checked that we are receiving trial tokens in the app, but users confirm that they bought the apps. Some are able to reset somehow, but most can't.

This error is also described here (see first review by Rod):

Other recent feedback from user:

"I tried all the usual suspects. Reloaded excel. Refreshed apps in excel. Attempted to repurchase through excel to see if it would kick in. Restarted the computer."

"If my memory is correct, I believe the yellow trial warning box that drops from the top of the screen that prompts you to purchase (which I believe is queued when you try to load data instead of just watching the demo) eventually caught on itself and the 'buy' button turned into a 'refresh' button (or something very similar to that) and where it said '...you are on a trial, click to buy...' it changed to 'you may have purchased this, click to refresh'. As soon as I did that it worked, I think the problem is that the 'you may have purchased this, click to refresh' button isn't appearing on command as I had to try the things I mentioned to get it to kick through (and who knows if what I did did anything, or if it eventually fixed itself). Hope that is clear."

Already opened an issue with office apps support team, but now new information yet.

Can only imagine annoying and demotivating this should be to Office users.
