Are there device limits or is it a user limit?
Your plan determines the number of users, and each user can be signed in on one device at a time:
Lite and Standard: 1 user
Premium: 2 users
Ultra: 4 users
So, while there’s no hard limit on the number of devices you can use over time, only the number of users in your plan can be signed in simultaneously - one device per user.
Can I use multiple devices?
Yes! You can switch between devices freely. However, you can only be signed in on as many devices as your plan allows based on its user limit.
Note: Projects do not carry over between devices, but your personal presets will.
