Warning
Angular version 13 & 14 are officially outdated, so this version is not supported anymore.
ng update @ngx-pwa/local-storageImportant
If your project is actually in a version < 12, please do the other migrations first in an incremental way. The version 9 migration is especially important, as a wrongly done migration could lead to the loss of all previously stored data.
Angular 13 dropped IE 11 support, and so this library too.
