The dashboard, Chart of Accounts, Transactions and Connected Accounts pages are styled with class names that begin with ad-, and some browser ad-blockers hide any element whose class starts with that prefix, leaving a blank page or missing buttons. Try disabling your ad-blocker for your Sprwt admin domain or opening the page in a private window without extensions. If the page is still blank, the data requests may be failing – look for a red message such as Invalid Permissions ! or You don't have acess to this module! and check your role and module.
