Anyone had problems with their login to Mobile apps?

Hello Community, I’ve downloaded “Mendix Developer”, “Mendix Mobile” from the Google Play app store, and none of these allow me to log in with the credentials I use to log into the Web browser on my computer. I had changed my password earlier in the day to see if this would resolve the issue, but that didn’t. I can’t move further to evaluate or consider Mendix until this is resolved. Are there any prerequisite on Mobile devices? I tested on a phone and a tablet the access to one of the three apps I created on my computer (through the browser) using the tutorials, and nothing works. The “About” on the web developer portal shows Mendix Studio 2.0.546, and Mendix Studio version
