Michael’s log

Service is cool

Transfer

Simply perfect, thank you

It sucks

Took i don’t know how many tries to get it to work

It is very comprehensive to use

It is well designed and user friendly. Thank you.

Don’t like the new set up

I do not like the new account setup where all of the transactions are lumped together. I especially do not like having the church’s account transactions linked and displayed together with my personal account transactions.

The accounts need to remain separate so that transactions can be reviewed and tracked individually. This new setup is confusing and makes it more difficult to manage and reconcile each account properly.

Please change the setup back to the original format, where we could review each account and its transactions separately. The previous setup was much clearer, more organized, and easier to manage.
