Hi.
I’ve a problem concerned the uploading pdf files on airtable with my phone and not with my computer.
The PDF files is the same files.
Both solution work on my computer ( web view ).
I delete the writing on airtable for test it on my phone, and i’ve problem. Do again with my computer, no problem… and with my phone… problem…
APP Block :
I tested the 2 solutions ( UP1 and UP2 ), let time by a wait block for let time to do the upload, but nothing happenned with my phone and the app stay in the step of the loading visible is true.
In UP2, no writing “true” value in airtable in Q2Valid
