Viber depreciates Public accounts and migrates customers to Сommunity chats.
Here is an update we have received from Viber regarding migration affecting Viberer app functionality
- The deep link viber://pa?chatURI=<URI> should still work to start 1:1 conversations
- It isn't possible to add a bot to a community or group, and we do not plan to add this functionality.
- There aren't any specific new limitations that should be caused in this process.
As a conclusion, if you use a deep link to your Viber bot or than you are fine. There will be no public account to link users directly to the chat, so you have to publish it somewhere else, e.g in the pinned chat post.
