eBay app no way to set default sort order of item to PRICE - lowest first?

[fusion01k]

On my laptop it is default to lowest price first, but on eBay app on my phone it is set to BEST MATCH.  If I change it to Price -lowest first, the next search reverts back to BEST MATCH.  How can I change this?
