Crash upon first startup(android)

[RKGamer]

Hi, so I bought the laptimer app(gran prix edition), and downloaded it. Upon startup it simply flashed a black screen and crashed, with no other explainantion whatsoever... I`m using a Xiaomi 11 Ultra running non rooted Miui 12.5, there are google service in this smartphone and yeah I tried reinstall and restart and all that...

Anyone would have a idea on what`s probably happening? Would be much appriciated

Hello,

It looks like LapTimer is not compatible with the Xiaomi. Please uninstall and request a refund following the instructions on http://www.gps-laptimer.de/products It is basically sending the Google Order Number (GPA....) to me.
