Apparently AccountRight 2018 does not have single user log in as AccountRight Premier v19 has. If you don't put your data file on the cloud, you have to go into each user and set them to read only and then afterwards go into each user and set them back to read/write.
Can single user log in please be added to AccountRight 2018.
Not everyone wants to put their data file on the cloud and we shouldn't be inconvenienced for not doing so.
