I would refer to Darth's opinion on this but my guess is along the lines of @jakoyoh629 's answer.

I remember uninstalling my Zeus app a while back for some ridiculous reason and the channels force closed and the funds eventually reappeared onchain, all Kudos to Zeus for contingency plans for retards like me.

Now, Phoenix uses splicing which I believe is different to Zeus but ypur funds maybe forced closed?

As i say I'd take @DarthCoin advice over mine 🤣🤣
