Why is it difficult to remove the Xiaomi Smart Band 9 when in the pebble mode?

The pebble is designed with soft rubber to wrap around the band for stability during running.
If you encounter difficulty in removing it, please follow these instructions:
1. The band has a curved surface with a quick-release groove. Use your fingernail to gently insert into the groove and pull the band;
2. If you still find it hard to remove the band even after locating the groove, open the user manual and take out the green pry piece (found in a transparent bag inside the manual). Gently push the pry piece forward into the groove. Use and store the pry piece carefully for future use.
