I cannot see raids

Hi,I play Pokemon go on lenovo tablet with android 4. All goes fine, but I cannot see raid battles. If there is a raid in near gym, I can see it on my friends mobile phone, but on my tablet I see normal gym without raid. I can normally enter, see pokemons inside, feed them etc. I tried reinstall the game, but nothing have changed. Have somebody expected this problem?Could you please help me?

I have never used a tablet but go thru all the normal tricks. Check your GPS is on High Accuracy.Erase your Cache and/reinstall. Sometimes power savers cut of your GPS to a lower setting…Good Luck.

I just saw this was September. Duh.
