Just retrieved the record from several years ago, find out it is now possible to upgrade the plants. I thought I just random updated some of the plants where possible, the hint just keep coming up once I finished a new level as shown below and I can do nothing about it. I can only restart the game to get to the next level but the hint will show up once a new level is done.
@ruazi123 Have you tried the troubleshooting? Make sure to take a screenshot of your Player ID in case something goes wrong.
