If you are trying to make any customizations to the Resco Field service Mobile app, you would encounter few strange issues at times which can block development.
Note: In case you are unaware, the silverlight based woodford solution just works in IE(Tested in IE11) and that too in non-incognito mode i.e. if you are working in incognito mode, the solution will fail to load.
Also many times the solution gets loaded but towards the end it gives you error saying CRM metadata failed to refresh and then all you can access is your Profile tab (and other non dev related tabs).
I haven’t been able to find a solution to the above problem except for restarting IE again, seems like a caching issue.
