I've seen mention of Santander but not of Lloyds bypassing the root detection. After much trial and error it's quite simple and my method will bypass both Santander and Lloyds. If bypassing Santander just do the same for the Santander app as ive said to do with Lloyds.
Having flashed a new rom and following my steps again I received the detection message again but was resolved by using the Canary build of Magisk Manager.
To get Magisk Manager Canary click the link below:
Once installed, open Magisk Manager and go to
settings > Update Channel > Canary
Go back to Magisk home screen and swipe down to check for updates, you'll receive an update for the canary build. Once you update follow the guides original steps below.
<--End of update-->
In Magisk Manager Settings:
Enable Magisk Hide
Enable Sytemless Host
And if the option is available select "Hide Magisk"
Download my exported blacklist from:
Then in adaway click the 3 dots in the top right to open the menu, select "Your Lists" then press the menu button again in the top right and press "Import all lists" and select the file you downloaded.
With the urls added go back to the adaway main screen and press "Download Files and Apply ad blocking" and Reboot device. If "Download Files and Apply Ad Blocking" doesn't appear, click "check for updates" and then download them which will do the same thing.
Once your phone has restarted install the Lloyds Banking app but don't open it. Go into Magisk Manager and select Magisk Hide from the menu and tick the Lloyds Banking app. Reboot phone and Lloyds should work perfectly!
I managed to do this from researching other threads and adding my own bits in so credit due elsewhere as well, as usual you can follow this guide but do so at your own risk, i take no responsibility
