We have configured shared iPad with temporary guest mode, but guest can't login due to storage problems. What is the best configuration in the DEP profile für this (max. number of users, standard or storage quota)?
It depends on quantity of users and how many storage could be used to each one. We force to max 9 users on iPads with 64Gb, but if your shared users can install a lot of apps or make a lot of local files like videos will be empty your storage quickly.
