Planapple Mobile does not work with private browsing
Most often, this is because you have enabled Safari's "private browsing" mode. To use Planapple Mobile, please follow Apple's instructions to turn private browsing OFF.
If you are not using Safari, or this does not solve the problem, please make certain your browser's settings (including any privacy extensions you may have installed) allow Planapple to use "localStorage" and that your device's storage is not full.
