We used to have no way of knowing which projects were getting traction or not with our target audience so we had nothing at all but hope that one day this would change, if only for us! The interface was intuitive enough even when using an iPad version (no kidding!). It's very easy just like any other tool you use online - create your project/project page; upload files etc.. There are some minor issues here & there such as missing icons in certain areas where they should be visible however most likely will get fixed soon since it has been brought up many times by their customers who love them. I think anyone trying out these services can see how great everything works from uploading design elements right through content creation until finalizing each product before going live into production mode. So far i haven't come across anything bad about working with warp japan nor did my clients ever complain either time. Great service overall especially now given its COVID lockdown situation. The team at warp japan are very professional, they understand our business needs perfectly well! They have great experience in designing websites that work for us as an organisation too - we've had some really good success stories with them so far (and I think this will continue!). We're also working together to develop new products which has been fantastic fun :) Nothing much but everything works out ok when you get it right from start!!
