I don't even see how to add a new account on their android app. 🤔
Discussion
Hmmm... on iOS its very smooth.
1. Click your avatar.
2. Click "..." menu and add as many accounts as you want.
3. Then you will have all the avatar sit next to each other with a one Click switch.
Pretty flawless.
Does it allow you to share as another account? Or do you have to copy-paste things around?
Yes, if by share you mean post, no copy/paste needed, complete app switch.
It is like having multiple Primal apps. Relays change, you can post as another account, as it you are using your primary one.
Nice! Do they merge multiple feeds as one as well?
That they don't do.
tbh, that would be confusing. I personally won't want that.
