Pokemon Go to Remove Regieleki Elite Raid Timed Research

Trainers, the next Elite Raid event starts this Sunday, but unfortunately, you won’t be able to access nor complete the Timed Research.
Regieleki is the next Elite Raid Boss in Pokemon Go, scheduled to take over Elite Raids on April 9, 2023. Regieleki will hatch at different times: 11 AM, 2 PM, and 5 PM local time.
If you remember, during the Regidrago Elite Raid event players had a chance to access and complete the exclusive TImed Research after defeating Regidrago in Elite Raids. Well, some players didn’t get the Timed Research even though they’ve defeated Regidrago. Niantic and Pokemon Go acknowledged the mistake and sent 2 Premium Battle Passes, and 1 Lucky Egg.
Now, to prevent this from happening once again, they decided to remove the Regieleki TImed Research.
Trainers, we'd like to inform you that we will be removing the Timed Research for the upcoming Regieleki Elite Raid while we work to improve its intended distribution method. This Timed Research will be offered at a later date which will be announced in the near future.
