since few days my Android Gmail shows no messages in the primary folder as you can see on the screenshot below.
All the other tabs (social, updates) are running fine. I have another google account configured on this phone and all tabs are showing fine also.I confirm (just in case) that I actually have a lot of emails in this tab and I can access them correctly when using the desktop web app.Also I still have a notification when a new email arrives, I can click on the notification and see the email, but as soon as I close it I can't access it anymore since the app always show that I have no emails in primary tab.
Of course I have tried to reboot my phone with no success.
Does anyone has ever experienced it and how can I fix it please?
Thank you for your help.
