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.

Nightmare at the outset, better later. fields jump all over the place when you're trying to fill them in, most frequently hiding behind the keyboard. the "Next" button always hides too. Need to be remade with a proper responsive interface. After initial issues and badly posed questions it got a bit better, although it took 10 attempts to accept my passport was real so that element probably needs work. Wish I didn't have to download an app for this process either and that I could use a website.

Doesn't work. First go it looked like it had uploaded docs then failed to submit them with no reason given. Second go that worked, but when trying to enter text I get no cursor or keyboard. My solicitor told me it would take a few minutes to complete this, seems like that's a sales pitch Thirdfort have failed to deliver. The chatbot suggestions didn't work and the support team are only available when I'm at work. Have emailed them but judging by other reviews I'm not holding out much hope.
