Before I updated Viber, it was possible to see my location under text messages, but now it isn't shown. Is it a technical issue or just the outcome of the updated version?
The location feature is still available. You just have to activate it when you're typing, but after you click on the little arrow, wait a few moments to get a GPS lock and that's it. The next message that you will send will have the Location access embedded into.
You can also send the Location through using the instructions on the following page: https://support.viber.com/customer/en/portal/articles/1415447-how-to-send-your-location
