I have a problem on my website
strangesounds.org. When I publish a new post, it immediatly appears on ‘Desktop’ but is delayed by around 4 hours on ‘Mobile’.
I use Cloudways+Cloudflare Pro+WPSuperCache
When I purge Cache on Cloudways (Varnish) and Cloudflare (Purge Everything), then the posts reappear on ‘Mobile’ too…
Server-level cache @Cloudways: Varnish; Cache Lifetime: 4h (14400s); no other types of caching enabled (Redis or MamCached).
Cloudflare: TTL: 2min (120s)
WP Super Cache: Cache Time-Out: 60s; Timer: 90s.
I tried without WP Supercache and I had the same problem. So I think it is not related to that Wordpress Plugin.
It seems that the Varnish Cache Lifetime of 4 hours isn’t ‘overwritten’ on ‘Mobile’ and if I don’t clear the Varnish Cache, the posts will only appear 4 hours later.
Is that possible?
Is there a way to solve this issue?
