Marketplace kicks me out
when using my IPad, Marketplace kicks me out several times. This just recently started happening. iPad is up to date.
iPad Air 3, iPadOS 14
Facebook Marketplace is known to be frequent source of problems.
The usual remedy is to delete the Facebook/Marketplace Apps from the iPad - and then perform a restart of the iPad prior to reinstalling the Apps from the App Store.
