Concern with a few apps workability

My concern is will i be able to use samsung pay if i install this os?

This is not an OS. This is just another app in your phone.

I’m unable to edit tiles tried it from settings and home screen to unable to add apps and can’t connect phone to bllocdesk as well

Editing app drawers seems to have a bug. Devs are working on it.
As for bllocdesk connection, what is the error you are getting?

Not getting any error but unable to pair i tried it multiple times.

I arranged my app drawer by tap and hold on the icon and moving it to another folder

Another issue is the apps are not being arranged automatically by cataogries
