Earlier today I downloaded the app for Sidecqar to my phone. Upon signing in, I inadvertently put in my landline #. Up[on realizing the eror, I hit the back button, corrected the error and hit Next. Nothing happened and I thought it was because I entered the wrong # before. I called SIdecar support and talked to a very nice lady who explained that they were having some problems with the app and answered some questions I hads. A very positive 1st experience indeed!
