things not working on Sequoia

oclp 2.0.2

sequoia 15.0.1

mob 14.3

I installed sequoia 10 days ago. Was working fine, but did not try everything. Since, I realize not working:

• Freeze at opening
  • Message (sequoia bug, right?)
  • Contacts (time to time)
  • Maps
• not working
  • Copy / past between devices
  • Continuity across devices (iPhone 12 Pro with 18.0.1)

Thanks for help.
