Dual apps support

[moshpirit]

I have two different accounts for WhatsApp and I use Dual apps for that, but it's very annoying that every time I open this app two things may happen:

• If I open the "original" one I get this window asking which one do I want to use.
• If I try to open the "duplicated" one it says it can't find the app even though they both are visible in the apps drawer and I can see both icons.
