The app was a big challenge even for the test team, which for the first time tried internal testing in the form of 12 people locked in a room all day and going through both planned and random scenarios. KMM and the dream shared module was the biggest challenge for the iOS team, who needed to familiarize themselves with the new concept and solve unexpected bugs with freezes and incompatibilities. After this experience, but we are already enthusiastically looking forward to the next project where we will be able to use KMM. Strapi is an amazing tool. But only if you know Node.js and are in control of it. A difficult challenge for mobile developers and analysts was collaboration across multiple departments and coordination with the BE team. As such, we had Strapi deployed in versions 3 and 4, and many things and parts worked differently than we expected. We often had to debug where the error probably occurred and how to bend the boxed solution for our needs. Here we were saved by the great patience and determination of the mobile team to bring things to a successful end.
