Armpit dressing keeps coming off

Is anyone else having trouble with the dressing for underarms following SNB mine won’t stay on I’m sweating bad in this heat probably not best time to have this done during a heatwave!!! and they just keep peeing off from the crease any tips!?

I redressed mine using dressings from Boots.  I did it every couple of days.  By day 8 or 9 I left the dressing off

Did it today hopefully I should get a couple of days till I can leave it off!
