SAP Fiori Launchpad: all tiles open the same app

Hello,

I have a strange SAP Fiori Launchpad tiles behavior.

The process is as follows:

1. I load FLP in a browser

2. Run any app by pressing the tile. That app is displayed.

3. Press "Home" icon in the top left, return to the FLP main page with tiles

4. Run another app (press another tile), but the first app opens.

That's it, from now on doesn't matter which tile I press, the same first app is displayed.

In all cases the url is correct, so if after item 4 in the list above I refresh the page, the correct app is displayed.

How do I fix this?

Thanks.
