Can't find a solution regarding element click selector problem

Hi y'all,

for a research regarding gym trends in Germany, I need to scrape the website, phone number and of course the name of gyms from a few sites.
Everything is going great, but with this particular site there is a problem.
There are 1514 gyms on the page, but it always stops at 501 gyms - so I guess there is a problem with the "load more" - button.
I followed every step in the tutorial and as I said, until 501 it works.

Any help would be so great!

Hi there!

If you didn't notice, page starts to lag hard once you press load more button more than 11 times, I would recommend you to increase delay up to 10 seconds (10000 ms) for page to successfully load the results.

Hi iconoclast,

thank you so much!

Works fine now, really appreciate your advice:)

Best regards,

Actually, I just had a look at the data again - it stops at 501, even with the increased delay.

You got any idea how to proceed?

Thank you so much for your time and advice!
