Dear community,

The view in the bottom bar disappears when I use the application in my browser. Indeed, when I use the application on a browser, the bottom bar disappears and the icons appear in the menu at the top left. This is very new, I noticed it on applications created since this week. This is not the case on my old apps. I do not understand what is happening or how to solve this problem. Could you please, help me ?
Thank you in advance for your help,

Best regards
