I’m looking for a good solution to clone/sandbox an app, so I can use it with multiple accounts.

I recently got a separate phone number, and also a whatsapp account, for work-related stuff. Turns out whatsapp’s own account switching thing is very unreliable and often doesn’t deliver any notifications for the “inactive” account.

I remember using Island a long time ago, but unfortunately that one hasn’t been updated in 3 years. I’m using parallel space right now, which at least delivers my notifications, but often super late and includes ads, which also isn’t ideal.

Are there any good cloning solutions left, preferably with decently quick notifications? (open source would also be a big plus ofc)
