Update your iPhone or iPad Software To Avoid Issues With Location This is being posted just in case there are Players using Older iOS Game Devices.
Starting just before 12:00 a.m. UTC on November 3, 2019,* some iPhone and iPad models introduced in 2012 and earlier will require an iOS update to maintain accurate GPS location. This is due to the GPS time rollover issue that began affecting GPS-enabled products from other manufacturers on April 6, 2019. Affected Apple devices are not impacted until just before 12:00 a.m. UTC on November 3, 2019.
*12:00 a.m. UTC on Sunday, November 3, 2019 = 8:00 PM EDT on Saturday, November 2, 2019.
This applies to iPhone 4, iPhone 5, and some older iPads (see Link) IMPORTANT:
For iPhone 5, an update is required to maintain accurate GPS location and to continue to use functions that rely on correct date and time including App Store, iCloud, email, and web browsing. If the update to iPhone 5 is not completed by November 3, 2019, you will be required to back up and restore using a Mac or PC in order to update because over-the-air software updates and iCloud Backup will not work.
