If your tablet is not a Wacom it is not officially supported by Animate at this stage and most likely you won't be able to do anything.
You can try an updated driver from manufacturer and playing with all settings that may relate to pen input in the OS Control Panel.
Some people have reported some success, but they never really go in detail how they get their tablets to work and never come back to help others.
Thank you! Yes, im using XP-PEN G430 tablet, but 1d ago its worked. Idk what happened today. Some1 advice to open drivers first than a programm but it doesnt work.
