I am stuck in a continuous 'Sign In'-loop on my Android Phone for several mobile apps: Notes & Projects.

This is how it goes:

I fill in the login information, hit enter and it asks me to 'Choose an account', or 'Add an account'. I tried both options several times. However, whether I select the correct account, or I click 'add account' I am always being brought back to the same 'Sign In' page. So, I sign in again and the same thing happens over and over. In short: I can not use the apps. Please, how can I break this continuous loop?

As a side-note: In general I find the "Session Expired" feature rather unhandy. Certain mobile apps I use sporadically, since I do most of my work on my desktop. But when I do it is a nuisance to have to sign in each time. I found myself in a situation where I quickly needed to add a Note about a parking spot number on a large multi leveled parking area at the airport. When I opened Notebook is says: "Session Expired". At that time I didn't remember the long, complicated (as recommended by Zoho) password. I had to resort to an other app.
