Issues with new NFC (beta)

Hi, testing this new NFC out, i have issues
first: i think this is just a cosmetic issue, when i open HA client on my oneplus, i goto NFC options, i click on ‘write nfc tag’ , when i am in that submenu, when i then click the back button of my oneplus, it just generates a new identifier, instead of going to the previous menu
while i click on the back button itself in the topbar, then it goes back to the previous menu…

second: do i need release 114 for this? i used automation below, but i receive this error :

2020-08-12 09:05:31 ERROR (MainThread) [homeassistant.components.mobile_app.webhook] Received invalid webhook type: scan_tag

created also issue here :

you need to be on HA 0.114 for NFC to function

Ok, time to update
