For anyonebtrying to move their sats to phoenix and keeps getting a payment failed / rejected message.

Your inbound capacity is probably not enough and you will need to enlarge your channel. (Check you Lightning Channel capacity in settings)

The network fees needed for this is around 15k sats and the default fee limit in app is 5k sats.

So if you are ok with paying quite a lot to get more inbound liquidity, raise your max fee setting accordingly, if not, then at least you know why. 🥲
