———————————————————————————
there are 2 bugs to report
odb2 VLINKER MC+

• every time I start carlinkit and open abrp it is impossible to access the ODB2, I have to delete it and add it again, then it works, but if I turn off the device when I turn it back on it fails
• If I put ABRP in the background to access another application (music, calls, etc) despite removing all energy optimization and background ABRP stays "frozen" and when opened it reads the ODB2 again
