Variable 'bitmap_array' must be const in order to be put into read-only section...

Upon uploading the code, I get an error. Sorry in advance for the long copy and paste, but here's the message.

This report would have more information with

option enabled in File -> Preferences.

Nvm, just had to add an additional const to each of the lines so that

bitmap.h:
PROGMEM const unsigned char* bitmap_array[] = {
Would be
PROGMEM const unsigned char* const bitmap_array[] = {

RetroWatchArduino_no_button:
PROGMEM const char* weekString[] = {"", "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
PROGMEM const char* ampmString[] = {"AM", "PM"};
to
PROGMEM const char* const weekString[] = {"", "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
PROGMEM const char* const ampmString[] = {"AM", "PM"};

To solve the problem: variable 'bitmap_array' must be const in order to be put into read-only section by means of 'attribute((progmem))'

PROGMEM const unsigned char* bitmap_array[] = {

You must change it as: PROGMEM const unsigned char* const bitmap_array[] = {

Good luck!!
