The third-party widgets you installed worked without a hitch But suddenly they're grayed out? This could happen if you're too aggressive with them.

There isn't a limit to the number of Widgetsmith widgets it is possible to include however, tests have shown that when you add too many they'll eventually crash.

A glitch or iOS 14 limitation that caps the amount of resources an app widget from a third party could use hinders Widgetsmith from showing the right glances when you have added excessive.

Solution: When it happens, you should erase the most recent widgets and then reboot your iPhone. If the problem continues I'm afraid you'll need to remove the Widget Smith application and then restore it. This means you'll have to rebuild your widgets starting from the beginning!
