I brought this up a few days ago too. 
Here for your reference:
The only way that I can think about getting ‘around’ this issue is to either email the link into a recipient’s inbox (and pray that app doesn’t use an in-app browser) OR via SMS.
SMS will kinda guarantee a fix to the problem (I think) but it adds a load of complexity and potentially cost.
Glide can’t really fix iOS restrictions… I’ll continue searching for an answer. Until then either email / sms or a quick video explaining how users can open the link in Safari etc.
