@jacob-l , can you please create a list of sub-issues that will reflect the activities you believe are necessary to complete the initial porting of the app to OpenSilver 3.2? Just write down the titles for the sub-issues if they are self-explanatory. If you need one or two more sentences for some of them, please add a description as well.

The goal is to identify the scope that has been left and make some plans.
Thanks.
