Fees normal and stable in my opinion its the first beta I've tested and I use my phone as normal. Few minor issues I've noticed slightly slower when scrolling but bearly noticeable.
Banking apps I've tried Monzo, Revolut, MBNA, TSB, Curve, AMEX, SPay and all works normal. Some good lock features won't work and maybe Google pay won't work so bare in mind.
Any other questions let me know.
