Hello,
Thank you for checking the community.
Per checking your account, it seems you logged in from the website (lastpass.com) which is designed as "desktop". That is how you switched the device type of the account.
Please, access the account back to mobile by accessing the app. You have 1 remaining switch. If you want to access LastPass on both device types, you must upgrade toLastPass PremiumorLastPass Families.
Let us know if further assistance is required.
Thank you,
Karol | Customer Care
