I Cannot Sell Items in My Hay Day Roadside Shop Despite Advertising

I play Hay Day on Android, and for the past 4–5 days I have not been able to sell items in my roadside shop. Even though I advertise my products, they do not appear in the newspaper, and my added friends cannot see them either. I tested this with another account and confirmed that my listed items are invisible.

To fix the issue, I first waited a few days, then deleted and reinstalled the game, but nothing changed. I contacted support through the in-game help and also sent an email to Supercell’s support team, but I only receive automatic replies and no real solution. Since my products would not sell, I had to remove them by spending diamonds, but the problem still continues even when I put items back.

My account details:

Supercell ID: u***

In-game code: #q***

On the same device, my other account works fine without this issue, so the problem is specific to this account. I would like my account to be fixed and an explanation of why this problem is happening.
