Navionics boating app cannot connect to gps

Navionics boating app cannot “see” the gps.
Asks to enable gps while it is enabled.

Magicearth has no problem accessing the gps
Anyone got a fix?

Update to 3.0.1 didnt help

check if this is enabled:
Settings → Apps → Navionics → Permissions → Location → use exact location [x]
