How to rectify these issues I face in WhatsApp
Some three months back I bought a new phone. As I did not want to lose my chats, as a cautious measure I made the new phone as Linked Device. (I did not have any backup in my Google account, and was unsuccessful when I tried).I regularly used the new phone for WhatsApp and periodically used it in the old phone as required to keep the Linked Device active. It was all okay till yesterday.
Yesterday evening suddenly the linked device showed me logged out. So I again linked the phone using the primary device. But from then on I faced the following problems-
1. I am not able to delete any chats on my Linked Device
2. Even after reading the chats, after closing the app and opening it again, all those chats showed as unread in the secondary device.
3. Even if I deleted the chats in the primary device it does not reflect in the linked device.
I updated WhatsApp on my Linked device and primary device and again logged out and re-linked, but the problem persists.
Can you suggest a sure remedy for this?
