Hi @stefan ,
Currently, the Bolt Cloud pages for the programmed HTML pages are not mobile optimised. Due to this the user experience is not very smooth. Hence we have blocked the access via the mobile browser.
We are not looking to optimise the pages for the mobile browsers. Instead, we will be making it a feature of the Bolt IoT mobile apps to access the programmed pages in the first quarter of 2019.
In the meantime, however, our team is also working on building a project that can demonstrate how you can control your Bolt on the mobile phones using Bubble. Bubble allows you to build apps visually, without requiring any code. I shall share the project with you in a couple of weeks once it is ready.
