M5Unified 0.2.6 causes compilation issues with M5Dial #165
Description
Hi,
After a really frustrating morning trying to do the initial setup for the M5Dial, I have realized that using the latest version (Released yesterday, may 16th 2025) causes compilation issues when using the M5Dial package.
Unless the version is pinned to m5stack/M5Unified@0.2.5 it will fail to compile with errors like:

Note that I am using platformio, but this issue also happens compiling through Arduino IDE.
I think there must be something wrong either from the M5Dial library or M5Unified. If M5Dial is not compatible with versions >0.2.5 then it should be stated in the M5Dial documentation, tutorials, etc.
