I went into the app and it said that I was using a number old version and that I needed to up date. I updated the app and went to continue adding the data they required but now the only page I can see it the notice page telling me to update the app? I even uninstalled and reinstalled the app but after inputting my phone number and getting security code it flipped straight back to the 'update app' notice page! How this is meant to make things easier I don't know?

This is hands down one of the worst apps I've ever had the misfortune to have to use. in order to add my DOB I cannot directly add it on android - I'm forced to click back month by month through the years. Given I'm 50 years old this is hundreds of clicks. Hopeless, I guess user testing is unheard of in legal saas startup land.

We are so sorry for this experience! Having to tap back month by month to reach your year of birth is far from ideal. This issue is down to the standard Android date picker, but we have taken this on board and are updating the app so you can enter your date of birth easily in the next release. Thank you for your feedback.

This app would be a lot more convenient if there was at least the option of using a PC or laptop for all the text entry. The first authorisation text failed to arrive after 15 minutes, the next one arrived straight away. The screen for entering my name has a load of blank space between the text entry boxes making me think each name was entering each name as a separate form. That's as far as I've got with the app so far, don't know why I'm being asked to review it in the middle of the process.

Hi, thank you for your feedback. I will ensure this is shared with our Product teams. I'm sorry to read the text did not arrive at first. We have made some improvements very recently to how the text boxes present on the screen. If you would like to share any more feedback, please get in touch via feedback@thirdfort.com. Kind Regards, Thirdfort.
