TWRP on Mix 3, encryption question


Hello, i have installed twrp 3.2.3 0214 by wzsx150, wiped data and decrypted the phone.

Then i installed the previous EU rom (9.3.14), but when i tried to install the latest update, twrp asks for my pin password to decrypt the phone.
I thought that this version of twrp worked fine. Is there another version that works ok without needing the password each time, meaning that it decrypts the phone without encrypting it again? Thanks in advance!
Hello
Can u share the link for the twrp ?
So i can update my mix 3 to

Thank u
 
If you want to flash a new rom you must remove data encryption. If at TWRP opening you see your data partition stay encrypted (check it with file explorer.) you must apply format data/yes in the wipe section of twrp and then install your new rom.
If TWRP is well working it should be encrypting again after reboot.
Thats not true.
Do u have a mix 3 ?
