hi, since yesterday, i have problems syncing with gmail. i receive all the gmail emails without none problem, and the emails are correctly readed (on my android). but when i receive another email, all previously received emails are marked unread (another time), even if i delete (on my android). i mark read, or delete, or delete the "received" label from emails, but the next time i receive a email, it's marked unread if i access to my gmail account via pc and i mark as read, or deleted, the mails are correctly processed and the next time i receive a email are not marked unread at phone. my gmail config are unchanged since a month... ideas ?
