I noticed that my page/onlineshop seems to load quite slowly on mobile. I already optimized anything I could in the past and always get a 95-100 lighthouse score on desktop which is great I guess. Still I cant manage to get it above 60-70 on mobile and I think thats too slow?

Unfortunately I'm not very experienced and have absolutely no idea where the problem is located. I would be very very thankful if someone could take a look and maybe give me at least a direction where I should focus on.

If you are able to, I'd recommend running your DNS through Cloudflare. They actually have a plan specifically for WordPress that is $5 USD roughly a month?
