Already tried. Everything works: both several sats and larger transactions. But given the comments on this thread, I won't be using this cryptocurrency wallet.

Dude, like, half the functionality of a wallet is sending funds.

If you haven't tried sending, you've barely tried the wallet at all.

Sending can break down in high onchain fee environments bc of how many submarine swaps Muun does

It cannot be used for many things that lightning is used, like login for example.

Choice in favor of Muun 

Yes, but it works great with Lightning. At least he gets any amount of sat. Haven't tried sending yet.
