This could be associated with running out of memory on the device due to the large number of active eForms. The memory depends on the hardware&browser and is not only used by LOGitEASY, but also by other websites. You can see the used memory under My Logs window.
iPad Safari has only 2.5MB total offline memory available, while Windows/MacOS Chrome has 5MB. To clear up memory, please finalize and approve active eForms. Once you do that, these eForms will not be loading into the My Logs screen (you can still edit them after finalizing and approving, by accessing them individually from the workspace).
If you are using other websites offline or are using the same iPad for eForms with different usernames, memory will fill up faster. To clear history and website data on the iPad, go to Settings, Safari, Clear History and Website Data. However, when you do that, make sure you are ONLINE and eForm data have been synchronized.
